Which of the following is true?A. Modern wind turbines generate electricity for homes and businesses and for sale to utilitiesB. New wind power capacity added during 2010 reached 39GW, more than any other renewable technologyC. At least 52 countries increased their total existing capacity during 2010D. At the end of 2010, the world's largest operating onshore wind farm (almost 0.8 GW) was located in the United States.  A & C  B & C  All of the above  A & D

Select the best evidence to support the statement "Financial incentives from the federal government are partly responsible for the growth in wind energy in the United States." There may be more than one correct choice.From 2008 to 2014, the United States led all other countries in the amount of electricity generated by wind. U.S. wind power totaled nearly 168 million megawatthours during 2013, about three times more than the wind power generated in the United States in 2008.A major contributor to increasing U.S. wind power in recent years has been the federal production tax credit. The amount of U.S. electricity generated from wind has also increased because of state governments' renewable portfolio standards that require a percentage of their states' electricity supply to come from wind power and other renewable energy sources.

Currently, only 0.8% of total global energy supplies come from wind. How much energy could wind turbines potentially capture?100TW400TW800TW

Which of the following is true?A.More than a hundred counties added solar photovoltaic (PV) capacity during 2010B.Solar hot water/heating capacity increased by an estimated 25 GW worldwide in 2010C.The EU dominated the global PV market, led by Italy and particularly GermanyD.Canada is a world leader in solar-power research, development and commercialization.  A & B  All of the above  A & C  None of the above

"Capacity," in the diagram, is the maximum rate of electricity production that was possible for all the wind turbines in each country.In 2013, Spain had wind power capacity of 23,000 megawatts (MW). But it didn't achieve that rate of electricity output at any time during that year. Explain why.

Many countries are annually improving their renewable energy generation from wind power. On average, how much larger is China’s onshore wind capacity additions in comparison to the EU between 2018 and 2020? Use International Energy Agency data and round to the nearest whole number.
