- "Our dependence on fossil fuels amounts to global pyromania, and the only fire extinguisher we have at our disposal is renewable energy." – Hermann Scheer.
- "There is one forecast of which you can already be sure: someday renewable energy will be the only way for people to satisfy their energy needs. Because of the physical, ecological and (therefore) social limits to nuclear and fossil energy use, ultimately nobody will be able to circumvent renewable energy as the solution, even if it turns out to be everybody’s last remaining choice. The question keeping everyone in suspense, however, is whether we shall succeed in making this radical change of energy platforms happen early enough to spare the world irreversible ecological mutilation and political and economic catastrophe." – Hermann Scheer, Energy Autonomy: The Economic, Social and Technological Case for Renewable Energy (2006)
- "First, once the renewable infrastructure is built, the fuel is free forever. Unlike carbon-based fuels, the wind and the sun and the earth itself provide fuel that is free, in amounts that are effectively limitless."
- "Second, while fossil fuel technologies are more mature, renewable energy technologies are being rapidly improved. So innovation and ingenuity give us the ability to constantly increase the efficiency of renewable energy and continually reduce its cost."
- "Third, once the world makes a clear commitment to shifting toward renewable energy, the volume of production will itself sharply reduce the cost of each windmill and each solar panel, while adding yet more incentives for additional research and development to further speed up the innovation process."
– Al Gore, Our Choice, 2009, p. 58.
- "We are entering a new era, one of rapid and often unpredictable climate change. In fact, the new climate norm is change. The 25 warmest years on record have come since 1980. And the 10 warmest years since global recordkeeping began in 1880 have come since 1996."
- "The effects of rising temperature are pervasive. Higher temperatures diminish crop yields, melt the mountain glaciers that feed rivers, generate more-destructive storms, increase the severity of flooding, intensify drought, cause more-frequent and destructive wildfires, and alter ecosystems everywhere."
- "...the transition from coal, oil, and gas to wind, solar, and geothermal energy is well under way. In the old economy, energy was produced by burning something — oil, coal, or natural gas — leading to the carbon emissions that have come to define our economy. The new energy economy harnesses the energy in wind, the energy coming from the sun, and heat from within the earth itself."
– Lester R. Brown, Plan B 4.0: Mobilizing to Save Civilization, 2009.
- "The variability of sun, wind and so on, turns out to be a non-problem if you do several sensible things. One is to diversify your renewables by technology, so that weather conditions bad for one kind are good for another. Second, you diversify by site so they're not all subject to the same weather pattern at the same time because they're in the same place. Third, you use standard weather forecasting techniques to forecast wind, sun and rain, and of course hydro operators do this right now. Fourth, you integrate all your resources — supply side and demand side..." – Amory Lovins
- "Because the wind blows during stormy conditions when the sun does not shine and the sun often shines on calm days with little wind, combining wind and solar can go a long way toward meeting demand, especially when geothermal provides a steady base and hydroelectric can be called on to fill in the gaps". – Mark Z. Jacobson and Mark A. Delucchi. Scientific American, November 2009, p. 43.
- "Renewable energy is proving to be commercially viable for a growing list of consumers and uses. Renewable energy technologies provide many benefits that go well beyond energy alone. More and more, renewable energies are contributing to the three pillars of sustainable development – the economy, the environment and social well-being – not only in IEA countries, but globally."
- "Renewable energy is derived from natural processes that are replenished constantly. In its various forms, it derives directly from the sun, or from heat generated deep within the earth. Included in the definition is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources."
– International Energy Agency, Renewable energy... into the mainstream, 2002.
- "Perhaps because of its technical, economic, and thermodynamic advantages, a renewable power sector would have six benefits over one reliant on conventional power plants, including (1) lower negative externalities per kWh, (2) more stable and predictable fuel prices, (3) fewer greenhouse gas emissions, (4) less water use, (5) improved efficiency, and (6) greater local employment and revenue." – Benjamin K. Sovacool and Charmaine Watts. The Electricity Journal, May 2009, Vol. 22, Issue 4, p. 99.
- "... renewable electricity technologies present policy makers with a superior alternative for minimising the risk of fuel interruptions and shortages, helping improve the fragile transmission network and reducing environmental harm. These smaller and more environmentally friendly generators cost less to construct, produce power in smaller increments and need not rely on continuous government subsidies. They generate little to no waste, have less greenhouse gas emissions per unit of electricity produced and do not contribute significantly to the risk of accidents." – Benjamin K. Sovacool, Journal of Contemporary Asia, 40(3), 2010, p. 371.
- "The solar-power market offers perhaps one of the greatest opportunities among its clean-tech peers. Not only is the worldwide solar market growing by 30% to 50% per year, but the same technologies that enabled the semiconductor and computer revolution are now being leveraged in the solar market." – Ron Pernick and Clint Wilder. The Clean Tech Revolution, 2007, p. 20.
- "Today’s green buildings use some 30% less energy than their comparably sized nongreen counterparts (some save much more), and they’re generally brighter, healthier, and more aesthetically pleasing. Often built with little or no additional up-front cost, green offices, for instance, pay back not only in energy savings but also in greater employee retention, attendance, and productivity." – Ron Pernick and Clint Wilder. The Clean Tech Revolution, 2007, p. 21.
- "Wind projects boost local tax bases, helping to pay for schools, roads and hospitals. Wind projects also revitalize the economy of rural communities by providing steady income to farmers and other landowners. Each wind turbine contributes $3,000 to $5,000 or more per year in rental income, while farmers continue to grow crops or graze cattle up to the foot of the turbines." – American Wind Energy Association (2009). Annual Wind Industry Report, Year Ending 2008 pp. 9–10.
- "A wind farm, when installed on agricultural land, has one of the lowest environmental impacts of all energy sources. It occupies less land area per kilowatt-hour (kWh) of electricity generated than any other energy conversion system, apart from rooftop solar energy, and is compatible with grazing and crops." – Mark Diesendorf, in Dissent, No. 13, Summer 2003/04, pp. 43–48.
- "People do not want electricity or oil ... but rather comfortable rooms, light, vehicular motion, food, tables, and other real things."
- "There exists today a body of energy technologies that have certain specific features in common and that offer great technical, economic, and political attractions ... 'soft' energy technologies [which are] flexible, resilient, sustainable, and benign. They rely on renewable energy flows that are always there whether we use them of not, such as sun and wind and vegetation."
- "Soft technologies' matching of energy quality to end-use needs virtually eliminates the costs and losses of secondary energy conversion, [and] the appropriate scale of soft technologies can virtually eliminate the costs and losses of energy distribution."
– Amory Lovins, Soft Energy Paths, 1977, pp. 38–40.
- "The sunlight ... that strikes Earth’s land surface in two hours is equivalent to total human energy use in a year. While much of that sunlight becomes heat, solar energy is also responsible for the energy embodied in wind, hydro, wave, and biomass, each with the potential to be harnessed for human use. Only a small portion of that enormous daily, renewable flux of energy will ever be needed by humanity."
- "Improved energy productivity and renewable energy are both available in abundance—and new policies and technologies are rapidly making them more economically competitive with fossil fuels. In combination, these energy options represent the most robust alternative to the current energy system, capable of providing the diverse array of energy services that a modern economy requires. Given the urgency of the climate problem, that is indeed convenient."
– Christopher Flavin in Worldwatch Institute (2008). Building a Low-Carbon Economy in State of the World 2008, p. 80.
- "Perhaps the quickest, easiest, and most profitable way to reduce electricity use worldwide — thus cutting carbon emissions — is simply to change light bulbs. Replacing the inefficient incandescent light bulbs that are still widely used today with new compact fluorescents (CFLs) can reduce electricity use by three fourths. The energy saved by replacing a 100-watt incandescent bulb with an equivalent CFL over its lifetime is sufficient to drive a Toyota Prius hybrid car from New York to San Francisco."
- "Over its lifetime, each standard (13 watt) CFL will reduce electricity bills by roughly $30. And though a CFL may cost twice as much as an incandescent, it lasts 10 times as long. Since it uses less energy, it also means fewer CO2 emissions. Each one reduces energy use by the equivalent of 200 pounds of coal over its lifetime."
– Lester R. Brown. PLAN B 3.0: Mobilizing to Save Civilization 2008, p. 215.
- "Ethanol creates U.S. jobs, cleans the air, strengthens national security – and best of all, it is here right now. Every day, ethanol producers are developing technological improvements to increase efficiency, reduce water use, and boost the amount of energy derived from corn kernels or from cellulosic biomass. Ethanol is not a 'someday' fuel. It is the renewable, clean-burning alternative we have to gasoline today."
- "Moreover, advancements in ethanol production are quickly opening the door for the commercialization of cellulosic ethanol and other advanced biofuels."
– Ethanol is Here Today Renewable Energy World, 19 August 2010.
- "Wind power is widely seen as the source of renewable energy with the best chance of competing with fossil-fuel power stations in the near term." – The Economist Technology Quarterly, 12 June 2010, p. 12.
- "In 2009, a total of 38,103 MW of new wind installations were recorded, with the total installed global wind power capacity now standing at 160 GW. This represents an increase in cumulative installations of 31%, and a 35% rise in the rate of annual installations. This was the fifth year in a row with record installations, albeit a slightly lower rate compared with the 42% achieved in 2008." – BTM Wind Market Report Renewable Energy World, 20 July 2010.
- "Renewable energy provides 18 percent of total net electricity generation worldwide. Renewable energy generators are spread across the globe, and wind power alone already provides a significant share of electricity in some regions: for example, 14 percent in the U.S. state of Iowa, 40 percent in the northern German state of Schleswig-Holstein, and 20 percent in the nation of Denmark. Some countries get most of their power from renewables, including Iceland (100 percent), Brazil (85 percent), Austria (62 percent), New Zealand (65 percent), and Sweden (54 percent)."
- "Solar hot water provides an important contribution to meeting hot water needs in many countries, most importantly in China, which now has fully 70 percent of the global total (180 GWth)... Worldwide, total installed solar water heating systems meet a portion of the water heating needs of over 70 million households. The use of biomass for heating continues to grow as well. Notable is Sweden, where national use of biomass energy has surpassed that of oil. Direct geothermal for heating is also growing rapidly."
- "Renewable biofuels are meanwhile making inroads in the transportation fuels market and are beginning to have a measurable impact on demand for petroleum fuels, contributing to a decline in oil consumption in the United States in particular starting in 2006... The 93 billion liters of biofuels produced worldwide in 2009 displaced the equivalent of an estimated 68 billion liters of gasoline, equal to about 5 percent of world gasoline production."
– Christopher Flavin in REN21 (2010). Renewables 2010 Global Status Report p. 53.
- "One of the new forces propelling renewable energy development is the potential to create new industries and generate millions of new jobs. Jobs from renewables now number in the hundreds of thousands in several countries. Germany, which has led renewable energy development for more than a decade, had more than 300,000 people employed in renewables industries in 2009, almost equaling the number of jobs in the country’s largest manufacturing sector, automobiles."
- "Most of the large fiscal stimulus packages launched since late 2008 to combat the global recession have included significant funding for renewable energy. This has prevented a more pronounced economic downturn in the United States and has created a new industry almost from scratch in South Korea, which devoted four-fifths of its fiscal stimulus to the green economy. In total, nearly $200 million in green stimulus funding has been allocated to renewables and energy efficiency."
- "The 1,230 gigawatts (GW) of renewable power generating capacity in place at the end of 2009 now constitutes just over 25 percent of total generating capacity worldwide. This is over three times nuclear generating capacity and roughly 38 percent of the capacity of fossil fuel-burning power plants worldwide."
– Christopher Flavin in REN21 (2010). Renewables 2010 Global Status Report p. 52.
- "The European Union has committed itself to getting 20% of its electricity from renewable energy sources, mainly wind power, by 2020. In America the Department of Energy reckons that wind could provide a similar proportion of the country's electricity by 2030. China recently tripled its wind-capacity target to 100 GW by 2020." – The Economist Technology Quarterly, 12 June 2010, p. 12.
- "The sun provides more energy in one hour than all humanity uses, in all forms, in a single year. Sunlight can provide us with its own resolution to our energy problems. The only transformation required is for humanity to reduce, or end, consumption of stored solar (as fossil fuels) and, in its place, use freely available 'fresh' solar". – David S. Findley (2010). Solar power for your home, p.12.
- "To truly transform our economy, protect our security, and save our planet from the ravages of climate change, we need to ultimately make clean, renewable energy the profitable kind of energy." -Barack Obama, Address to Joint Session of Congress, Feb. 24, 2009
- "We need to push ourselves to make as many reductions as possible in our own energy use first.. and that takes time. But we must do this quickly.. the climate will not wait for us." -Rupert Murdoch
- "The use of solar energy has not been opened up because the oil industry does not own the sun".-Ralph Nader
