The document details three primary cooling methods for thermoelectric power plants in the US: once-through, wet-recirculating, and dry-cooling. It highlights that while once-through systems have high water withdrawals and wet-recirculating systems have higher consumption, dry-cooling can reduce water consumption by over 90% despite higher costs and lower efficiencies. As of 2008, recirculating systems were the most common in terms of both generator count (56%) and electricity generation (45%).

The paper examines historical cases from the Roman Empire, Early Modern Europe, and the Far East to argue that long-term economic growth is possible within renewable energy systems if demand, supply, and trade are managed through sound government policy. It contrasts successful management in Germany and Japan with failures in China, and assesses the technical potential of global renewable resources compared to current energy consumption.

The report analyzes Chile's transition toward non-conventional renewable energy (NCRE), noting that while installed capacity in the Central Interconnected Grid (SIC) nearly doubled between 2007 and 2009, the sector remains hindered by high market concentration and financial risks. It details the impact of Law No. 20.257, which mandates a clean energy quota of 5% by 2010 and 10% by 2024, and evaluates CORFO's incentive programs. The document highlights a critical tension between the growth of clean energy and a simultaneous increase in coal-fired generation, which threatens Chile's climate goals and long-term competitiveness.

In 2008, Alabama imported 79% of the coal used for its electricity generation, resulting in a net expenditure of $1.39 billion. The state's electricity mix was dominated by coal (51.1%) and nuclear (26.7%). Alabama spent the most per person ($297) and the most relative to gross state product (0.82%) on net coal imports compared to other US states. To reduce this dependence, the document suggests investing in energy efficiency—noting that Alabama spent only 49 cents per person on such programs in 2007—and utilizing renewable resources which could technically meet 56% of the state's 2008 power demand.

In 2008, Arkansas imported all the coal used by its power plants, resulting in $463 million leaving the state, primarily to Wyoming. The state's electricity mix was 47.5% coal, with Entergy Arkansas and its White Bluff plant being the largest importers. The document argues that Arkansas could reduce this dependence and stimulate its local economy by adopting energy efficiency resource standards and renewable electricity standards, leveraging its potential for wind, solar, geothermal, and biomass energy.

In 2008, Mississippi relied on coal for 34.6% of its electricity generation, importing over 70% of that coal and spending $457 million out of state. The document argues that the state can reduce this dependence by investing in energy efficiency—noting that 2007 ratepayer-funded efficiency spending was 1,400 times lower per person than spending on imported coal—and by utilizing local renewable resources such as forestry by-products, switchgrass, solar, and geothermal energy.

The report describes Feed-in Tariffs (FITs) as a policy tool to accelerate renewable energy deployment by providing guaranteed, long-term payment rates and grid access to producers. It highlights successful implementations in Denmark and Germany, while noting that Spain's high rates led to overinvestment and a subsequent global drop in solar panel prices. In the US, the report notes a lack of federal policy but identifies local efforts in Gainesville, Florida, and California, concluding with design recommendations such as using trial phases and binding caps to avoid windfall profits.

The report analyzes the Chilean electricity sector's transition toward clean energies, specifically Non-Conventional Renewable Energies (NCRE). It details the current dominance of fossil fuels and large hydro, the impact of the 2008 Law 20.257 establishing renewable quotas, and the role of CORFO in providing pre-investment incentives. While noting a positive investment climate and growing interest from foreign investors, the document identifies significant barriers, including high economic risk due to the lack of stable long-term pricing, high market concentration, and limited access to financing for small developers. It concludes by recommending a more comprehensive national strategy that internalizes environmental externalities and enhances technical and human capital.

The report finds that existing climate variability already costs Kenya up to 2% of GDP annually, with future climate change potentially adding a loss of 2.6% of GDP per year by 2030. Adaptation needs are estimated at $500 million per year for 2012, rising to $1-2 billion per year by 2030. The study also identifies significant opportunities for low-carbon growth, noting that over 80% of selected energy-related emission reduction options can be realized at a net negative cost.

The document outlines the job creation potential of the clean energy economy, citing that renewable energy (RE) and energy efficiency (EE) industries created over nine million jobs in the U.S. in 2007. It provides specific employment projections for various technologies, including wind, solar, bioenergy, and geothermal, across U.S. states and international markets such as Germany, Brazil, and India. The text also compares these figures to employment trends in the fossil fuel and nuclear sectors and details U.S. legislative efforts, such as the Green Jobs Act of 2007 and the American Recovery and Reinvestment Act of 2009, to support workforce training and clean energy deployment.

The report projects that Minnesota will face significantly hotter summers, increased flooding, and agricultural threats if current emissions trends continue. Under a high-emissions scenario, the state could see a 12°F increase in average summer temperatures by the end of the century, with Minneapolis-St. Paul experiencing nearly 70 days over 90°F per summer. These changes are expected to increase heat-related mortality, worsen air quality through higher ozone and particulate levels, and disrupt farming via heat stress and pest expansion. The document advocates for a transition to renewable energy, increased energy efficiency, and a federal cap-and-trade program to mitigate these risks.

The report projects that Missouri will face significantly hotter summers, increased flooding, and agricultural disruptions if heat-trapping emissions continue to rise. It highlights severe risks for St. Louis, including extreme heat waves and deteriorating air quality, and suggests a combination of state-level energy efficiency and federal climate legislation to mitigate these effects.

The report projects that Ohio will face significantly hotter summers, increased flooding, and agricultural disruptions if current emissions trends continue. It highlights severe risks to public health from heat waves and ozone pollution, and warns of crop and livestock stress. The document advocates for a transition to clean energy through stronger renewable electricity standards, updated building codes, and federal cap-and-trade legislation.

The Climate 2030 Blueprint proposes a combination of an economywide cap-and-trade program and complementary sector-specific policies to reduce U.S. greenhouse gas emissions. The analysis argues that these measures can achieve deep carbon cuts while generating significant net savings for consumers and businesses, reducing oil dependence, and maintaining robust economic growth.

The report provides a comprehensive cost-benefit analysis of 40 low-carbon interventions in Mexico, focusing on electricity, oil and gas, end-use energy, transport, and agriculture and forestry. It argues that Mexico can stabilize its greenhouse gas emissions at 2008 levels by 2030 while maintaining economic growth, provided it overcomes institutional and regulatory barriers. The study highlights 'win-win' interventions with positive economic returns and significant co-benefits for public health and energy security.

The document presents a collection of data points from multiple research organizations arguing that renewable energy (RE) and energy efficiency (EE) sectors generate more employment per unit of energy or investment than fossil fuels. It highlights national and state-level projections in the US, such as the potential for 4.2 million new green jobs by 2038, and international examples from Germany, Spain, Brazil, and India. Specific technology sectors—including wind, solar, biofuels, and geothermal—are detailed alongside the impact of policy mechanisms like Renewable Portfolio Standards (RPS) and investment tax credits.

The Production Tax Credit (PTC) provides financial incentives for renewable energy facilities in the U.S., offering 2.3 cents per kWh for wind, geothermal, and closed-loop bioenergy, and 1.1 cents per kWh for other technologies. While the PTC has driven significant wind capacity growth and cost reductions, the document argues that Congress's pattern of allowing the credit to expire and then granting short-term extensions has created a 'boom-bust cycle' that jeopardizes financing, jobs, and long-term development.

The document advocates for a national Renewable Electricity Standard (RES) in the United States, describing it as a market-based mechanism that requires utilities to increase the share of electricity produced from renewable sources. It highlights economic benefits, such as saving consumers money and creating rural jobs, and environmental benefits, including the reduction of carbon dioxide and other harmful pollutants.

The document describes geothermal energy as a sustainable, baseload power source derived from Earth's internal heat. It details three types of power plants—dry steam, flash, and binary cycle—and the use of ground-source heat pumps for building climate control. While the U.S. is a global leader in capacity, largely centered in California, the text highlights emerging technologies like Enhanced Geothermal Systems (EGS) and co-production in oil and gas wells as keys to unlocking vast untapped energy reserves.

The document aggregates data from multiple polling organizations (including CNN, Gallup, and the Harris Poll) regarding public attitudes toward global warming. Key trends include a majority of U.S. adults viewing global warming as a proven fact caused by human activity, support for cap-and-trade systems and renewable energy mandates, and a growing belief that the U.S. should lead in reducing greenhouse gas emissions regardless of other nations' actions. Regional data highlights specific concerns in Florida regarding sea-level rise and in California regarding state-level emissions laws.
