The document analyzes the role of renewable energy in the Southern African mining sector, highlighting how energy instability and the high cost of diesel generators drive mining firms toward hybrid and private renewable solutions. While South Africa faces challenges from a reliance on coal and potential 'bridging' fuels like shale gas and nuclear power, the declining cost of solar and wind technologies, supported by the Renewable Energy Independent Power Producer Programme (REIPPPP), offers a viable path to reduce operating costs and increase energy security.

The document argues that current political emission targets are insufficient to prevent devastating climate impacts and that global GHG emissions must decline rapidly after 2015 to reach essentially zero by midcentury. It asserts that while such a transition is technically feasible and economically affordable, it requires a 'Great Transformation' of institutions and policy, including a global climate fund and a shift in agricultural systems from emission sources to sinks. The report emphasizes that industrialized nations must reduce their emission allocations to zero or negative levels by 2020-2030 to allow developing countries the remaining carbon budget necessary to expand energy access and alleviate poverty.

The document argues that the EU27 must reduce greenhouse gas emissions by 40% by 2020 and nearly 90% by 2050 relative to 1990 levels to meet its climate obligations. This requires a radical transition to renewable energy, the phase-out of fossil fuels and nuclear power, and significant improvements in energy efficiency across housing, transport, and agriculture. Additionally, the EU has an international obligation to finance mitigation in developing countries, estimated at 1% to 3% of its projected 2020 GDP. The brief concludes that while the costs are considerable, they are bearable and far lower than the potential economic losses from climate inaction.

The report '80 Gigawatts of Change' presents seven modeled scenarios for Egypt's electricity sector from 2015 to 2035. It compares a 'Business as Usual' (BAU) baseline against pathways focusing on decarbonization, energy independence, and decentralization. The analysis highlights that while centralized fossil-fuel-based models are cheaper in the short term, they risk 'carbon lock-in' and exacerbate energy access inequities. Conversely, decentralized and renewable-heavy pathways offer higher job creation and lower emissions but require significant initial investment and institutional reform. The report specifically warns against coal and nuclear power due to high water consumption, environmental risks, and low job creation relative to renewables.

The report analyzes the 'technological innovation system' (TIS) for solar PV and CCS, contrasting the EU's market-pull approach with the US's R&D-push focus. While solar PV has seen rapid growth and falling costs, it faces risks from fluctuating European subsidies. CCS is stalled in the 'valley of death' due to high capital requirements for large-scale demonstration and a lack of long-term climate policy, particularly in the US.

The report finds that companies in Latin America and the Caribbean (LAC) achieve a high average internal rate of return (IRR) of 17% on low-carbon investments, significantly outperforming European companies. Energy efficiency measures are the primary driver of emissions reductions, delivering an average IRR of 16.7%. The document also highlights that LAC companies are setting emissions targets that are, on average, 14% more ambitious than science-based recommendations. It argues that this strong business case should encourage regional governments, particularly Peru, to push for more ambitious international climate agreements.

The report argues that Concentrating Solar Thermal power (CST) is a viable large-scale, zero-carbon alternative to coal-fired power, particularly when combined with thermal storage to meet baseload demand. While currently more expensive than coal, costs are expected to decline through technology learning, R&D in materials and optical design, and economies of scale from larger plants. The document highlights that a carbon price of approximately $115 per ton of CO2 would make CST with 6 hours of storage economically competitive with coal. It emphasizes the need for stable policy support, such as feed-in tariffs, to bridge the current cost gap and calls for increased deployment in rapidly developing economies like China and India to alter their emissions trajectories. Additionally, the report notes that widespread CST adoption requires improved transmission infrastructure, specifically federal coordination in the U.S. and links between the EU and North Africa.

The paper examines three state-level solar irrigation schemes in India to identify lessons for Tamil Nadu's implementation of PM KUSUM Component C. It highlights challenges in farmer financing, trust in solar technology, and the impact of feed-in tariffs on water conservation, while recommending robust monitoring and adequate tariff assessments.

The paper identifies key factors and recommendations for achieving 'transformational' change in low-carbon energy, defined by large magnitude impact, non-linear growth, and long-term sustainability. Through the analysis of 20 case studies, the authors categorize experiences into transformational, potentially transformational, and missed opportunities, highlighting the roles of regulatory frameworks, financial incentives, and national ownership.

The document outlines a framework for matching policy instruments to the innovation stage of renewable energy technologies. It argues that grants are best for R&D and demonstration to manage high uncertainty, while loan guarantees suit commercialization and early deployment to share technical risk. Tax credits and feed-in tariffs are recommended for later innovation stages to offset upfront costs, and Renewable Electricity Standards (RES) are most effective for mature technologies in early deployment. The brief also emphasizes that a favorable regulatory environment is essential to prevent interconnection and pricing hurdles from undermining these incentives.

The document analyzes Japan's 'Warsaw Target' to reduce greenhouse gas emissions by 3.8 percent from 2005 levels by 2020. It finds that while this target represents a decrease in ambition compared to the earlier Copenhagen Pledge, it is likely achievable if Japan continues electricity-saving efforts and implements existing mitigation policies. The paper notes a lack of transparency regarding expected emissions reductions for specific policy measures and highlights a contradiction between the promotion of high-efficiency coal-fired power plants and Japan's long-term 2050 mitigation goals.

The paper analyzes the roles of OPIC and Ex-Im Bank in climate finance, noting that together they intermediated 37% (over $2 billion) of total US assistance to developing countries for climate activities between 2010 and 2012. It argues that tailoring financial instruments—such as loans, guarantees, and insurance—to specific sectoral risks can unlock private finance. The authors highlight a complementary relationship where OPIC often acts as a first-mover for high-risk projects, while Ex-Im Bank provides inexpensive concessional debt for more established players. Recommendations include increasing instrument flexibility, addressing institutional barriers like employee incentives and staffing, and improving coordination between public financial institutions to streamline due diligence and co-financing.

The paper analyzes 124 Chinese overseas investments in wind and solar energy across 33 countries, identifying that these investments are primarily driven by excess domestic manufacturing capacity, state-owned bank financing, and host-country incentives. While concentrated in developed nations like the US and Germany, investments also reach developing countries such as Ethiopia and Pakistan, with a significant portion focused on electricity generation via joint ventures.

The document argues that climate change disproportionately affects the world's poorest populations, particularly regarding food security and economic growth. It asserts that to limit warming to 2°C, a significant majority of known fossil fuel reserves must remain unused. Furthermore, it highlights that transitioning to renewable energy and energy efficiency can drive job creation and economic growth, citing examples from China and Germany's policy frameworks.

The document analyzes the relationship between national policy frameworks and the growth of solar PV and wind industries across five major economies. It contrasts the success of comprehensive, stable policies in Germany and China with the less effective, short-term 'patchwork' approach used in the United States. Data from 2005 and 2011 show that while China has achieved massive manufacturing capacity, Germany's stable legal framework has been a key driver for its industry, and the US lacks long-term national predictability due to incentives requiring frequent re-authorization.

The report outlines strategies for U.S. companies to adopt on-site renewable energy, focusing on solar, wind, geothermal, and solar thermal technologies. It details various ownership and financing models—ranging from direct ownership to third-party power purchase agreements—and analyzes the associated financial incentives, operational risks, and corporate benefits such as cost hedging and brand enhancement.

Tanzania has expanded its mini-grid capacity since 2008 through the small power producers (SPP) framework, now operating over 100 systems serving approximately 184,000 customers. While hydro is the most common technology, fossil fuel systems provide the majority of customer connections. The government has updated regulatory frameworks to better support solar and wind energy and attract private investment, including pegging tariffs to the U.S. dollar and lowering project size eligibility to 100 kW. However, challenges remain regarding cumbersome non-energy regulatory clearances, limited access to local commercial bank financing for domestic developers, and a lack of systematic data on socioeconomic impacts.

The report analyzes renewable energy adoption among the world's largest corporations, finding that 59% of the Fortune 100 and 63% of the Global 100 have set greenhouse gas (GHG) or renewable energy targets. Companies are driven by cost reduction, risk hedging, and consumer demand, utilizing a mix of Renewable Energy Certificates (RECs), Power Purchase Agreements (PPAs), and on-site investments. Key barriers include the need for cost parity with fossil fuels, internal competition for capital, and inconsistent government policies. The report recommends that corporations set time-bound targets and that policymakers extend incentives like the U.S. Production Tax Credit (PTC) and authorize third-party PPAs to accelerate the transition.
