With a vortex, of air created. By a shorter, less expensive. Structure. Space-based. Solar, power, Espie Espie is, the concept, of collecting, solar power in space using, an, SPS. That. As a solar. Power, satellite. Aura. Satellite. Power. System. For. Use on earth it has, been in research, since the early 1970s. SB. SP, would differ from current, solar collection, methods, in that demeans used to collect energy. Would reside on an orbiting, satellite instead. Of on Earth's surface. Some. Projected. Benefits of such a system, or a higher collection. Rate and a longer collection. Period due to the lack of a diffusing atmosphere. And night time in space. Topic. Renewable. Energy, industry. Total. Investment in, renewable, energy, reached. 211. Billion dollars, in 2010. Up from, 160. Billion dollars, in 2009. The. Top countries. For investment, in 2010. Were. China. Germany. The United States, Italy. And Brazil. Continued. Growth for the renewable, energy, sector as. Expected, and promotional. Policies. Helped the industry weather, the 2009.
Economic, Crisis, better than many other sectors. Topic. Wind, power companies. As of. 2010. Vestas. From denmark is the world's, top wind, turbine, manufacturer. In terms of percentage, of market, volume and Sinovel. From china is in second, place. Together. Vestas. And Sinovel, delivered, ten thousand, two hundred twenty. Eight megawatts. Of new wind power capacity in. 2010. And their market, share was twenty, five point nine percent. GE. Energy USA. Was in third place. Closely followed. By gold, wind another, Chinese, supplier. German. Enercon ranks. Fifth in the world and, has followed in sixth place by Indian, based Suzlon. Topic. Photovoltaic. Market. Trends. The, solar PV, market has been growing for the past few, years. According. To solar, PV, research, company, PV, in sites worldwide, shipment. Of solar modules, in 2011. Was around 25, gigawatts. And the shipment year-over-year, growth, was. Around 40, percent, the. Top 5 solar, module, players in 2011. Interns, our Sun tech First Solar Yingli. Trina, and sungan. The. Top 5 solar module, companies, possessed. 51.3%. Market. Share of solar, modules. According, to peep in sites market, intelligence report. The. PV, industry has. Seen drops in module, prices since, 2008. In, late. 2011. Factory. Gate prices, for crystalline, silicon, photovoltaic, modules. Dropped, below the $1, per w mark, the. $1.00, per W installed, cost is, often, regarded in the PV industry as. Marking, the achievement. Of grid parity, for PV. These. Reductions. Have taken, many stakeholders. Including. Industry, analysts. By surprise, and perceptions. Of current, solar power economics. Often lags behind reality. Some. Stakeholders. Still have the perspective that solar PV, remains too costly, on an unsubsidized. Basis, to compete with conventional. Generation, options. Yet. Technological. Advancements. Manufacturing. Process, improvements. An industry. Restructuring mean. That further price reductions. Are likely, in coming, years. Topic. Non, technical. Barriers. To acceptance. Many.
Energy, Markets. Institutions. And policies have, been developed, to support the production, and use of fossil, fuels. Newer. And cleaner technologies. May offer social. And environmental, benefits. But, utility, operators. Often reject, renewable, resources, because, they are trained to think only in terms of big conventional. Power plants. Consumers. Often ignore, renewable. Power systems. Because, they are not given, accurate, price signals, about electricity. Consumption. Intentional. Market, distortions. Such as subsidies, and unintentional. Market, distortions. Such as split incentives. May work against, renewables. Benjamin. Caso, vakul has argued, that some. Of the most surreptitious. Yet powerful. Impediments. Facing, renewable, energy, and energy efficiency, in. The United, States, are more about culture. And institutions than. Engineering, and science. The. Obstacles. To the widespread. Commercialization. Of renewable, energy, technologies. Are primarily, political. Not technical. And there have been many studies which, have identified. A range of non, technical. Barriers. To. Renewable, energy use these, barriers, are impediments, which put renewable, energy, at a marketing. Institutional. Or policy. Disadvantage. Relative, to other forms, of energy. Key. Barriers, include. Difficulty. Overcoming, established. Energy, systems, which includes, difficulty. Introducing. Innovative energy. Systems. Particularly. For distributed. Generations. Such as photovoltaics. Because. Of technological, lock-in. Electricity. Markets, designed, for centralized, power plants. And market, control, by established. Operators. As, the. Stern review on the economics. Of climate change, points, out, national. Grids are usually. Tailored, towards, the operation. Of centralized. Power plants. And favor, their performance. Technologies. That do not easily, fit into these networks, may, struggle to enter the market, even if the technology, itself. Is commercially. Viable. This. Applies to distributed. Generation, as, most grids, are not suited, to receive, electricity. From many small sources. Large. Scale, renewables. May also encounter. Problems, if, they are sited in areas, far from, existing. Grids. Lack, of government. Policy, support, which includes, the lack of policies. And regulations, supporting. Deployment. Of renewable, energy, technologies. And the presence, of policies. And regulations, hindering. Renewable, energy, development, and supporting, conventional. Energy development. Examples. Include subsidies. For fossil fuels. Insufficient. Consumer, based renewable. Energy, incentives, government. Underwriting, for nuclear, plant, accidents. And complex. Zoning, and permitting, processes. For, renewable, energy. Lack, of information. Dissemination. And consumer, awareness. Higher. Capital, cost, of renewable, energy, technologies. Compared, with conventional, energy. Technologies. Inadequate. Financing, options, for renewable, energy projects. Including. Insufficient. Access, to affordable financing. For, project, developers.
Entrepreneurs And. Consumers. Imperfect. Capital. Markets, which includes, failure, to internalize, all costs, of conventional, energy eg. Effects. Of air pollution risk, of supply, disruption. And failure, to internalize, all benefits, of renewable, energy, eg. Cleaner, air energy, security. Inadequate. Workforce, skills, and training, which includes, lack of adequate, scientific. Technical. And, manufacturing. Skills required. For renewable, energy production, lack. Of reliable, installation. Maintenance, and, inspection. Services. And failure, of the educational. System to provide adequate, training, in new technologies. Lack, of adequate codes. Standards. Utility. Interconnection. And net metering guidelines. Poor. Public perception. Of renewable, energy, system, aesthetics. Lack, of stakeholder. Community. Participation. And, cooperation. In energy, choices and renewable, energy projects. With such a wide range of, non-technical, barriers, there is no silver. Bullet. Solution, to, drive the transition. To renewable, energy, so. Ideally, there is a need for several. Different types of policy, instruments. To complement, each other and overcome, different, types of barriers, a policy. Framework must, be created, that will level the playing field and, redress the imbalance of. Traditional. Approaches, associated. With fossil fuels. The. Policy, landscape must. Keep pace with broad, trends, within the energy sector. As well as reflecting, specific. Social, economic. And environmental priorities. Some. Resource, rich countries, struggle, to move away from fossil fuels, and have failed thus far to adopt regulatory. Frameworks, necessary. For developing, renewable, energy, eg. Russia. Topic. Public. Policy. Landscape. Public. Policy. Has a role to play in renewable, energy, commercialization. Because. The free-market system has, some fundamental, limitations. As, the. Stern Review points. Out. In a, liberalized, energy, market, investors. Operators. And consumers. Should face the full cost of their decisions. But. This is not the case in many economies. Or energy, sectors. Many. Policies. Distort, the market, in favour of existing. Fossil fuel technologies. The. International. Solar energy. Society has, stated that. Historical. Incentives. For the conventional. Energy resources. Continue. Even today to bias, markets.
By Burying, many of the real societal. Costs, of their use. Fossil. Fuel energy systems. Have different production. Transmission. And end-use costs, and characteristics. Than do renewable, energy, systems, and new promotional. Policies. Are needed to ensure that renewable. Systems develop. As quickly and, broadly, as a socially. Desirable, Lester. Brown states, that the market, does. Not incorporate, the indirect. Costs. Of providing goods. Or services. Into prices, it does not value nature's, services. Adequately. And it does not respect, the sustainable. Yield thresholds. Of natural, systems. It also favors, the near-term over the long term thereby, showing limited, concern, for future generations. Tax. And subsidy, shifting, can help overcome, these problems though. Is also problematic, to combine different international. Normative. Regimes, regulating. This issue. Topic. Shifting. Taxes. Tax. Shifting. Has been widely discussed and, endorsed, by economists. It. Involves, lowering income. Taxes, while raising levies, on environmentally. Destructive, activities. In order to create a more responsive. Market. For. Example a tax, on coal that included, the increased, healthcare costs. Associated. With breathing, polluted air the costs, of acid rain damage, and the costs, of climate disruption. Would encourage, investment. In renewable, technologies. Several. Western, European, countries, are already shifting, taxes, in a process, known there as environmental. Tax reform, in 2001. Sweden. Launched, a new ten-year environmental. Tax shift designed, to convert 30 billion kroner. 3.9. Billion dollars. Of income taxes, - taxes, on environmentally. Destructive, activities. Other. European. Countries, with significant. Tax reform, efforts, are France Italy, Norway. Spain. And the United Kingdom. Asia's. Two leading economies. Japan. And China are, considering. Carbon, taxes. Topic. Shifting, subsidies. Just as there is a need for tax shifting. There is also a need for subsidy. Shifting. Subsidies. Are not an inherently, bad thing as many technologies. And industries, emerged, through government, subsidy, schemes. The. Stern Review explains. That of 20 key innovations. From the past 30 years only. One of the 14, was funded, entirely, by the private, sector and 9 were totally, publicly. Funded, in. Terms, of specific, examples. The internet was the result, of publicly, funded links among computers. In government, laboratories. And research institutes. And, the. Combination. Of the federal, tax deduction. In a robust, state tax deduction. In California. Helped to create the modern wind power industry, Lester. Brown has argued, that a world facing, the prospect of, economically. Disruptive. Climate, change can no longer justify, subsidies. To expand, the burning of coal and oil. Shifting. These subsidies, to the development. Of climate, benign energy, sources, such, as wind solar. Biomass. And, geothermal power. Is the key to stabilizing. The earth's climate the International. Solar energy. Society advocates. Leveling, the playing field, by, redressing, the continuing. Inequities, in public, subsidies, of energy, technologies. And R&D. In which the fossil, fuel and nuclear power, received, the largest share, of financial, support some. Countries, are eliminating. Or reducing climate. Disrupting. Subsidies. And Belgium, France, and, Japan, have phased out all subsidies, for coal. Germany. Is reducing. Its coal subsidy, the. Subsidy, dropped from five point four billion dollars. In 1989. To 2.8. Billion dollars. In 2002. And in the process, Germany, lowered, its coal use by 46. Percent. China, cut its coal subsidy. From, 750. Million dollars. In, 1993.
To 240. Million dollars, in, 1995. And more recently, has imposed, a high sulfur, coal tax. However. The, United, States has been increasing, its support for the fossil, fuel and nuclear industries, in, November. 2011, an, IEA, report entitled. Deploying. Renewables. 2011. Said subsidies. In green energy, technologies. That were not yet competitive. Are justified. In order to give an incentive to investing. Into technologies. With clear environmental. And energy security, benefits. The. IEA, s report, disagreed. With claims that renewable, energy technologies. Are only viable through, costly, subsidies, and not able to produce energy, reliably. To meet demand, a fair, and efficient, imposition. Of subsidies. For renewable, energies, and aiming at sustainable. Development. However, require. Coordination, and. Regulation. At a global, level as subsidies. Granted, in one country, can easily, disrupt, industries. And policies, of others thus, underlining, the relevance, of this issue at the World Trade Organization. Topic. Renewable. Energy, targets. Setting. National, renewable, energy, targets, can be an important, part of a renewable, energy, policy. And these targets, are usually, defined, as a percentage. Of the primary, energy and/or. Electricity. Generation, mix. For. Example the European Union. Has prescribed, an indicative, renewable. Energy, target, of 12%. Of the total EU energy, mix and 22%, of, electricity, consumption. By, 2010. National. Targets for individual. EU, Member States have also been, set to meet the overall target. Other. Developed. Countries, with defined, national. Or regional targets. Include, Australia, Canada. Israel, Japan, Korea. New, Zealand, Norway, Singapore. Switzerland. And some US states, national. Targets are also an important, component of, renewable, energy, strategies. In some developing. Countries. Developing. Countries with, renewable energy, targets. Include, China India. Indonesia, Malaysia. The, Philippines, Thailand. Brazil. Egypt. Mali and South, Africa. The, target. Set by many, developing. Countries, are quite modest, when compared, with those in some industrialized. Countries. Renewable. Energy, targets, in most countries are indicative, and non-binding, but they have assisted, government, actions, and regulatory. Frameworks. The. United, Nations, Environment. Program has suggested. That making, renewable energy. Targets, legally, binding, could be an important, policy, tool to achieve higher, renewable, energy, market, penetration. Topic. Leveling. The playing field. The, IEA, has, identified, three, actions, which will allow renewable, energy, and other clean, energy, technologies. To more. Effectively. Compete, for private, sector capital. First. Energy. Prices must, appropriately. Reflect, the, true. Cost of, energy. Eg through. Carbon pricing. So that the positive, and negative, impacts, of energy production. And consumption, are, fully taken, into account. Example. New UK, nuclear, plants, cost 92. Pounds and 50 pence per megawatt hour whereas. Offshore, windfarms. In the UK, are supported. With 74. Euros, and 20 cents per megawatt, hour at, a price of 150. Pounds in 2011. Falling, to 130. Pounds, per megawatt, hour in, 2022. In. Denmark. The price can be 84. Euros, per megawatt hour. Second. Inefficient. Fossil fuel. Subsidies. Must be removed, while ensuring. That all citizens, have, access to, affordable energy. Third. Governments. Must develop, policy. Frameworks. That encourage. Private, sector, investment. In lower carbon. Energy options. Topic. Green. Stimulus. Programs. In, response. To the global financial, crisis. In the late 2000s. The world's, major governments. Made green. Stimulus. Programs. One of their main policy. Instruments. For supporting, economic recovery. Some. 188. Billion dollars, in green stimulus. Funding, had been allocated to renewable, energy and energy efficiency. To, be spent mainly, in 2010. And in 2011. Topic. Energy. Sector, regulation. Public. Policy, determines, the extent to which renewable. Energy, BRE is to be incorporated. Into a developed, or developing countries. Generation. Mix. Energy. Sector, regulators, implement, that policy, thus. Affecting, the pace and pattern of re investments. And connections. To the grid energy. Regulators. Often, have authority to, carry out a number of functions, that have implications, for the financial. Feasibility of, renewable. Energy, projects. Such. Functions. Include, issuing, licenses, setting. Performance, standards, monitoring. The performance, of regulated. Firms determining.
The Price level and structure, of tariffs. Establishing. Uniform systems. Of accounts, arbitrating. Stakeholder. Disputes, like interconnection. Cost, allocations. Performing. Management, audits developing. Agency, human resources. Expertise. Reporting. Sector, and Commission activities, to government, authorities and, coordinating. Decisions, with other government, agencies. Thus. Regulators. Make a wide range of decisions, that affect the financial, outcomes, associated. With, reinvestments. In. Addition. The sector, regulator, is in a position to give advice to, the government regarding the full implications. Of focusing, on climate change or energy, security. The. Energy, sector, regulator, is the natural, advocate, for efficiency. And cost, containment, throughout, the process of designing, and implementing, read policies. Since. Policies. Are not self, implementing. Energy sector. Regulators, become, a key facilitator. Or blocker, of renewable. Energy, investments. Topic. Energy. Transition. In Germany. The, energy, went German, for energy, transition. Is the transition. By Germany, to a low-carbon. Environmentally. Sound reliable, and affordable energy. Supply. The. New system, will rely heavily on renewable. Energy particularly. Wind, photovoltaics. And, biomass. Energy, efficiency. And energy demand. Management. Most. If not all existing. Coal-fired, generation. Will, need to be retired. The. Phase-out, of Germany's, fleet of nuclear, reactors. To be complete, by 2022. Is a key, part of the program, legislative. Support, for the energy, wind was passed in late 2010. And includes, greenhouse, gas. GHG. Reductions. Of 80 to 95. Percent by. 2050. Relative, to 1990. And a renewable, energy target, of 60, percent by 2050. These. Targets, are ambitious. The, Berlin based Policy. Institute Agra. Energy, when noted, that while. The German, approach is not unique, worldwide, the speed, and scope of the energy, wind are exceptional. The, energy, wind also seeks, a greater transparency. In relation. To national. Energy policy, formation. Germany. Has made significant. Progress on, its GHG. Emissions, reduction. Target achieving. A 27, percent decrease, between, 1990. And 2014. However. Germany. Will need to maintain an average, GHG. Emissions abatement. Rate of 3.5. Percent, per annum to reach its energy, wind goal equal, to the maximum, historical. Value, thus far, Germany, spends, 1.5. Billion euros, per annum on energy, research, 2013. Figure, in an effort to solve the technical, and social, issues, raised by the transition. This. Includes, a number of computer, studies, that have confirmed, the feasibility, in a similar, cost relative. To business, as usual and given that carbon, is adequately, priced, of the energy, wind. These. Initiatives, go, well beyond European. Union, legislation. And the national, policies. Of other European states. The. Policy, objectives have, been embraced by the German, Federal Government and has resulted in, a huge expansion, of renewables. Particularly. Wind power. Germany's. Share of renewables. Has increased, from around 5%. In, 1999. To. 22.9%, in. 2012. Surpassing, the OECD. Average of, 18% usage. Of renewables. Producers. Have been guaranteed, a fixed, feed-in, tariff for 20 years guaranteeing. A fixed, income energy. Cooperatives. Have been created, and efforts, were made to decentralize. Control, and profits. The. Large energy, companies have, a disproportionately. Small share, of the renewables, market. However. In, some, cases poor. Investment. Designs, have caused bankruptcies. And low returns, and unrealistic. Promises. Have been shown to be far from reality. Nuclear. Power plants, were closed, and the existing, nine plants, will close earlier, than planned in 2022. One, factor, that has inhibited, efficient, employment, of new renewable energy. Has been the lack of an accompanying. Investment. In power infrastructure. To bring the power to market, it. Is believed. 8300. Kilometres, of power lines must be built or upgraded. The. Different, German states, have varying, attitudes, to the construction. Of new power lines. Industry. Has had their rates frozen.
And So the increased, costs, of the energy, wind have been passed on to consumers, who have had rising, electricity bills. Topic. Voluntary. Market, mechanisms. For renewable, electricity. Voluntary. Markets, also referred. To as green power, markets. Are driven by consumer, preference. Voluntary. Markets, allow a consumer. To choose to do more than policy, decisions. Require, and reduce the environmental impact. Of, their electricity, use. Voluntary. Green power products. Must offer a significant. Benefit, and value to buyers to be successful. Benefits. May include zero. Or reduced, greenhouse, gas, emissions. Other pollution, reductions. Or other environmental. Improvements. On power stations. The. Driving, factors, behind voluntary. Green electricity. Within the EU are the liberalized, electricity. Markets, and the res directive. According. To the directive, the EU, member states must ensure, that the origin, of electricity, produced, from renewables, can be guaranteed and, therefore, a guarantee. Of origin, must. Be issued article. 15. Environmental. Organizations. Are using the voluntary. Market to create new renewables. And improving. Sustainability. Of the existing. Power production, in. The, US the main tool to track and stimulate, voluntary. Actions, as greenie program. Managed, by Centre, for resource, solutions. In. Europe, the main voluntary. Tool used, by the NGOs. To promote sustainable. Electricity. Production as eco energy label. Topic. Recent. Developments. A number. Of events in, 2006. Pushed renewable. Energy, up the political, agenda including. The u.s. midterm, elections, in November which, confirmed, clean energy, as a mainstream issue. Also. In 2006. The, Stern Review made, a strong, economic case. For investing in, low-carbon. Technologies. Now and argued, that economic, growth need, not be incompatible with, cutting energy consumption. According. To a trend analysis. From the United, Nations, Environment, Programme, climate. Change concerns coupled. With recent, high oil prices and, increasing, government support. Are driving, increasing. Rates of investment. In the renewable, energy, and energy efficiency. Industries. Investment. Capital, flowing into renewable, energy, reached a record, 77. Billion dollars, in, 2007. With the upward trend continuing. In 2008. The. OECD. Still, dominates, but there is now increasing. Activity from, companies, in China, India, and Brazil. Chinese. Companies, were the second, largest recipient of, venture capital, in, 2006. After the United, States in, the. Same year India, was the largest, net buyer of companies, abroad mainly, in the more established. European, markets, new government, spending, regulation. And policies. Helped, the industry weather, the 2009. Economic, crisis.
Better Than many other sectors. Most. Notably, US, President. Barack Obama's. American. Recovery and Reinvestment Act. Of 2009. Included. More than 70, billion dollars in, direct spending, and tax credits for, clean energy and, associated. Transportation. Programs. This. Policy. Stimulus, combination. Represents. The largest federal, commitment, in US history for, renewables, advanced. Transportation, and, energy conservation. Initiatives. Based. On these new rules many, more utilities. Strength, they're clean energy, programs. Clean. Edge suggests. That the, commercialization. Of clean energy will help countries around, the world deal, with the current economic, malaise. Once. Promising, solar energy, company, Solyndra. Became, involved in a political, controversy, involving. US President. Barack Obama's. Administration's. Authorization. Of a, 535. Million dollars, loan guarantee, to the corporation. In 2009. As part of a program, to promote alternative, energy. Growth, the. Company, ceased all business, activity. Filed, for chapter, 11 bankruptcy, and. Laid off nearly all of its employees, in early September, 2011, in, his the 24th. Of January. 2012. State, of the Union address. President Barack. Obama, restated. His commitment, to renewable energy. Obama. Said, that he will. Not walk away from the promise of clean energy. Obama. Called, for a commitment, by the Defense, Department. To purchase, 1,000. Megawatts, of renewable energy. He. Also mentioned. The long-standing, Interior. Department. Commitment, to permit 10,000. Megawatts of renewable energy. Projects. On public land, in 2012. As of 2012. Renewable. Energy, plays a major role in the energy mix of many countries globally. Renewables. Are becoming, increasingly. Economic. In both developing. And developed countries. Prices. For renewable, energy technologies. Primarily. Wind power and solar power, continue, to drop, making renewables, competitive. With conventional energy, sources. Without. A level, playing field however high, market, penetration of. Renewables, is still dependent, on robust, promotional. Policies. Fossil. Fuel subsidies. Which are far higher than those for renewable. Energy remain. In place and quickly, need to be phased out United. Nations, secretary-general. Ban ki-moon. Has. That, renewable. Energy has, the ability. To lift the poorest, nations, to new levels of prosperity. In October. 2011, he, announced. The creation of, a high-level, group to drum up support for, energy access, energy. Efficiency. And greater use, of renewable, energy. The. Group is to be co-chaired, by candy, yum Killa the chair of u and energy, & Director, General, of the UN Industrial, Development Organisation. And, Charles, Holliday, chairman. Of Bank of America, worldwide. Use of solar power and wind power continued. To grow significantly. In 2012. Solar. Electricity. Consumption. Increased. By 58 percent to. 93. Terawatt-hours. Twh. Use. Of wind power in 2012, increased. By 18, point 1 percent to. 520. 1.3. Terawatt-hours. Global. Solar and wind energy installed. Capacities. Continued. To expand, even though new investments. In these technologies. Declined, during 2012. Worldwide. Investment. In solar power in 2012. Was, 140. Point four billion dollars. An 11, percent decline, from 2011. And wind power investment. Was down 10.1, percent to. 80 point, 3 billion dollars. But. Due to lower production costs for, both technologies. Total, installed, capacities. Grew sharply. This. Investment. Decline, but growth in installed, capacity. May again occur in 2013. Analysts. Expect the market to triple, by 2030. In. 2015. Investment. In renewables, exceeded. Fossils. Topic. 100%. Renewable. Energy. The, incentive, to use, 100%. Renewable, energy, for electricity. Transport. Or even, total, primary energy supply. Globally. Has been motivated. By global. Warming and other ecological as. Well as economic. Concerns. The. Intergovernmental. Panel on, Climate Change. Has said that there are few fundamental. Technological. Limits to integrating. A portfolio. Of renewable energy. Technologies. To meet most of the total, global energy demand, in. Reviewing. 164. Recent, scenarios, of future, renewable, energy, growth the, report, noted that the majority expected. Renewable, sources, to supply, more than 17, percent of total energy by, 2030, and, 27. Percent by, 2050. The highest forecast, projected. 43, percent supplied, by renewables. By 2030, and, 77.
Percent By. 2050. Renewable. Energy, use has grown, much faster than, even advocates. Anticipated. At the, national, level at least 30 nations, around the world already, have renewable, energy, contributing. More than 20%. Of energy, supply. Mark. Z Jacobson, professor. Of civil and environmental engineering. At. Stanford, University. And director of its atmosphere and, energy program says, producing. All new energy, with wind power solar. Power and, hydropower, by 2030. As feasible and, existing. Energy supply, arrangements. Could be replaced by 2050. Barriers. To implementing, the renewable, energy, plan are seen to be primarily. Social, and political not. Technological. Or economic. Jacobson. Says that energy costs, with a wind solar, water, system. Should be similar, to today's, energy, costs, similarly. In the United, States the independent. National Research. Council, has noted, that sufficient. Domestic, renewable, resources. Exist, to allow renew. Electricity. To play a significant. Role in future. Electricity, generation. And, thus help confront, issues related. To climate change, energy. Security. And the escalation, of energy, costs. Renewable. Energy, as an attractive. Option because. Renewable. Resources, available. In the United, States, taken. Collectively can, supply, significantly. Greater amounts. Of electricity. Than the total current, or projected. Domestic. Demand. The. Most significant. Barriers, to the widespread implementation, of. Large-scale, renewable energy. And low-carbon. Energy strategies. Are primarily, political and, not technological. According. To the 2013. Post-carbon. Pathways. Report, which reviewed, many international, studies. The key roadblocks, are climate, change denial, the fossil, fuels Lobby, political. Inaction. Unsustainable. Energy, consumption. Outdated. Energy infrastructure. And financial. Constraints. Topic. Energy. Efficiency. Moving. Towards, energy, sustainability. Will require, changes. Not only in, the way energy is supplied but in the way it is used, and reducing. The amount of energy required. To deliver various. Goods or services, as essential. Opportunities. For improvement, on the demand side of the energy, equation are. As rich and diverse as, those on the supply, side and often, offer significant. Economic benefits. A sustainable. Energy, economy. Requires, commitments. To both renewables. And efficiency. Renewable. Energy, and energy efficiency. Are said to be the twin. Pillars of. Sustainable. Energy policy, the. American. Council, for an, energy-efficient. Economy has, explained, that both resources, must, be developed, in order to stabilize and, reduce carbon dioxide emissions. Efficiency. Is essential, to slowing, the energy, demand growth so that rising. Clean energy, supplies, can make deep cuts in, fossil, fuel use if. Energy. Use grows too fast, renewable. Energy, development, will chase a receding, target. Likewise. Unless, clean, energy, supplies, come, online rapidly, slowing. Demand growth will only begin, to reduce total, emissions, reducing. The carbon content of energy, sources, is also needed. The, IEA, has stated, that renewable. Energy and energy efficiency. Policies. Are complementary. Tools for the development, of a sustainable, energy future and, should be developed, together instead. Of being developed, in isolation. Topic. See, also. Topic. Lists. Topic. Topics. Equals.
