The report argues that state renewable electricity standards (RES) are effective market-based tools that have driven significant growth in wind and solar capacity across the U.S. with minimal cost impacts on consumers. It highlights that these policies stimulate local economies through job creation in installation and manufacturing, provide new revenue streams for rural landowners, and stabilize electricity rates by removing reliance on volatile fossil fuel markets. While noting strong compliance rates, the document identifies transmission infrastructure, market oversupplies, and political opposition as primary challenges to further expansion.

The document argues that traditional utility business models, based on natural monopolies and centralized generation, are ill-equipped for the rise of distributed energy resources (DERs). It proposes a transition from a linear value chain to a 'value constellation' where the utility acts as a platform for value-based transactions. The paper outlines several potential models, including the Integrated Distributed Resource Manager, the Distributed Resource Finance Aggregator, and the Independent Distribution Network Operator, while discussing international examples of transactive grids and differentiated network charges.

The document examines the role of intellectual property rights (IPRs) in the global transition to clean energy, arguing that they are essential for motivating the private sector to innovate and lower costs. While acknowledging that IPRs can be a barrier for least-developed countries (LDCs) that rely on imitation, the author contends that the benefits of IPRs generally outweigh the costs. The paper highlights the concentration of clean energy patents in the US, Japan, and Germany, while noting China's rapid growth in the sector. It proposes a shift in terminology from 'technology transfer' to 'technology diffusion' and suggests a combination of IPR protection, public funding for basic research, and global finance mechanisms for demonstration projects to close the innovation gap in developing nations. A case study on the Kimberley Mechanism in South Africa illustrates how patenting can enable the development of low-cost concentrating solar power (CSP) components.

The report examines the growth of wind and solar power in the U.S. and globally, asserting that the technical challenges of variable energy sources are manageable. It highlights successful integration by utilities like Xcel Energy and countries like Denmark and Germany. The document details various tools for maintaining reliability—including geographic dispersion, improved forecasting, transmission upgrades, and energy storage—and cites studies suggesting that renewables could provide 80% of U.S. electricity by 2050.

The document argues that addressing the energy gap for the 'bottom of the pyramid' (BOP) requires a comprehensive approach to the innovation cycle, moving beyond simple technology development to include user-centric design, strategic deployment models, and the building of local institutional capabilities. It highlights that nearly 1.3 billion people lack electricity and 2.6 billion lack clean cooking energy, with significant health and climate costs associated with traditional biomass use. The author recommends leveraging diverse funding sources—including climate and health funds—and coordinating international initiatives to scale up sustainable energy solutions.

The report details climate finance in Germany across five key sectors. In 2010, the energy sector saw EUR 10.3 billion in climate-specific investment, dominated by private funding (98%) and renewable energy. The buildings sector received at least EUR 16.3 billion, primarily from households. The agriculture sector saw EUR 5.4 billion, almost entirely in renewables. Industry climate-specific investment was EUR 579 million in 2009, mostly for energy efficiency. Transport climate-specific investment averaged EUR 559 million, focused on energy-efficient vehicles. The report highlights the critical role of the public bank KfW in providing concessionary loans and the influence of the Feed-in Tariff on private investment.

The Stockholm Environment Institute (SEI) argues that traditional cookstove projects often fail because they focus on installation numbers rather than sustainable market transformation. SEI advocates for a user-centered design approach, combining qualitative ethnographic data with quantitative choice experiments to understand the social, cultural, and economic drivers of energy decisions. The briefing highlights the need for business models that enable local replication and examines the role of carbon finance and innovative fuel sources, such as ethanol micro distilleries in Ethiopia, to reduce reliance on biomass.

The report examines Viet Nam's investment incentive framework for renewable energy, analyzing financial, fiscal, and market-based supports. While the government has established a policy framework including tax exemptions and price subsidies, stakeholder interviews suggest these incentives have a limited effect on investment decisions due to low electricity off-take prices, regulatory opacity, and a lack of trust in government guarantees. The study highlights a contrast between the modest success of small hydropower and the struggles of wind and biogas projects to achieve financial viability.

In 2010, Germany invested at least EUR 37 billion (1.5% of GDP) in climate-specific measures, with over 95% of this funding provided by the private sector. Renewable energy generation was the primary recipient of these funds, totaling EUR 26.6 billion, while energy efficiency received EUR 7.2 billion in incremental investment. Public policy played a critical enabling role through the Feed-in Tariff (FiT), which paid approximately EUR 13.1 billion to generators, and concessionary loans from public banks, which accounted for 43% of renewable energy and 72% of energy efficiency investments. The report highlights a significant lack of systematic monitoring, reporting, and verification (MRV) for climate finance in Germany, noting that effectiveness is currently only evaluated for single programs rather than the broader landscape.

In 2010, Germany invested at least EUR 37 billion (1.5% of GDP) in climate-specific measures, with the private sector providing over 95% of this finance. Renewable energy generation was the primary recipient, attracting EUR 26.6 billion, while energy efficiency received EUR 7.2 billion in incremental investment. Public banks, particularly KfW and Rentenbank, played a critical role by providing EUR 16.5 billion in concessionary loans, which accounted for 43% of renewable energy and 72% of energy efficiency investments. The report highlights significant data gaps, noting that climate finance is not systematically tracked in public budgets or by the private sector, and recommends establishing a central registry and improved reporting standards to evaluate policy effectiveness.

The briefing examines the limitations of current U.S. federal tax incentives for renewable energy, which often require complex tax-equity arrangements. It proposes expanding the use of Master Limited Partnerships (MLPs) via the MLP Parity Act, seeking IRS clarification on Real Estate Investment Trusts (REITs), and utilizing the JOBS Act of 2012 to enable crowdfunding for small-scale projects to lower the cost of capital.

China has become a global leader in renewable energy investment and wind capacity, though it remains heavily dependent on coal for electricity and heat. While the 12th Five Year Plan sets targets for increasing non-fossil fuel use and reducing carbon emissions intensity, the country faces challenges such as grid connectivity for wind power and water shortages in arid provinces due to coal base construction. The government is also piloting emissions trading schemes in several cities and provinces as a precursor to a national system by 2015.

The document examines China's energy landscape as of 2012, highlighting its position as a global leader in renewable energy investment and wind capacity despite a heavy reliance on coal for electricity. It details the growth of the solar and wind sectors, the environmental and water-related costs of coal combustion, and the climate goals established under the 12th Five Year Plan, including targets for non-fossil fuel use and the implementation of carbon pricing mechanisms.

The document addresses the tension between the pursuit of a green economy and the existing international trade system. It argues that while Rio+20 provided general guidance, it failed to establish what constitutes 'appropriate state behaviour' regarding green industrial policies, such as subsidies and local content requirements. The author highlights a rise in trade frictions—including disputes between the U.S., China, and the EU over solar and wind technology—and asserts that the WTO's Dispute Settlement Mechanism is ill-suited to resolve these issues because they stem from a lack of international consensus on policy propriety rather than simple rule breaches. The text advocates for the creation of an institutional space, such as through UNCTAD, to evaluate the effectiveness of green tools and their impacts on trading partners, particularly developing nations, to ensure a just transition.

The solar water heater (SWH) industry in Barbados has achieved significant market penetration through a combination of early entrepreneurial leadership, consistent government fiscal incentives, and strategies to ensure consumer confidence. Since the 1970s, over 50,000 installations have saved consumers approximately US$137 million. Key drivers included the Fiscal Incentives Act of 1974, the Homeowner Tax Benefit, and government mandates for SWHs in public housing. The document argues that this success provides a foundation for broader acceptance of other renewable energy technologies and can be replicated in other sun-rich, oil-dependent countries if implemented as a coordinated system.

The report finds that federal incentives were critical for the viability of U.S. wind and solar projects in 2010, bridging roughly half the gap between generation costs and market prices. While cost reductions have made wind nearly viable with federal support alone by 2013, the report argues that current tax-based incentives are inefficient because project developers often lack the tax liabilities to fully utilize them, necessitating costly tax-equity financing. The authors propose replacing the Production Tax Credit (PTC) for wind with a Taxable Cash for Production (TCP) incentive and offering solar PV projects a 20% 1603 Cash Grant instead of a 30% Investment Tax Credit (ITC) to maintain support while significantly reducing costs to federal and state governments.

The document identifies five key realms for renewable energy policy: direct purchase mandates, improving the business case through financial incentives, removing non-price barriers, supporting research and development, and addressing grid intermittency. It recommends that Japan maintain its generous feed-in tariffs, expand demand response, and unbundle transmission from generation to increase competition. The report provides detailed international case studies from the US, Germany, and other nations to illustrate effective mechanisms such as Green Banks, loan guarantees, and carbon taxes.

An open letter from Scientists for Global Responsibility to the UK Secretary of State for Energy and Climate Change arguing that the Draft Energy Bill and current energy policies are unambitious and biased toward the nuclear industry at the expense of renewables and energy efficiency.

The document outlines four types of cool roofs—naturally cool, coated, insulated, and green (vegetated)—and details their capacity to reduce building energy use, mitigate the urban heat island effect, and lower greenhouse gas emissions. It highlights specific benefits such as a potential 15 percent reduction in air conditioning energy for single-story buildings and the ability of green roofs to manage storm-water runoff, illustrated by examples in Washington, D.C.

The report analyzes how California's 10 largest publicly owned utilities (POUs) met the 2010 RPS goal of 20 percent renewables. While collective RPS-eligible investments rose from 4.1 percent in 2003 to 18.8 percent in 2010, the quality of these investments varied. The authors emphasize that long-term contracts for new facilities are the most effective way to drive new clean energy development and stabilize rates. The report categorizes POUs into three groups: those 'sprinting ahead' (e.g., Silicon Valley Power), those 'on the right track' (e.g., LADWP), and those with a 'false start' (e.g., Imperial Irrigation District). It concludes with recommendations for the California Energy Commission (CEC) and POUs to prioritize long-term investments and improve reporting to meet the 33 percent RPS by 2020.
