12、Petroleum is a ( ) mixture of solid, liquid, and gaseous hydrocarbons that occurs naturally beneath the Earth's surface.
thick
flammable
yellobustion engines, meaning that much greater fuel economy is available using hydrogen in a fuel cell.
对
错
答案:
2、A fuel cell is a device that produces electricity from chemical fuels, in just one step. Unlike batteries, fuel cells don’t run down or need recharging. As long as there is a constant source of fuel and oxygen, fuel cells will continue to generate power. And they don’t burn the fuel – the electricity is produced directly.
对
错
答案:

7、Electrolysis can use wind, solar, geothermal, fossil fuels, biomass, nuclear, and many other energy sources.
对
错
答案:
8、Ways to produce hydrogen fuel include producing it from nuclear power, biomass, algae, artificial photosynthesis, direct solar and coal gasification.
对
错
答案:
9、Solar power causes no pollution at all.
对
错
答案:
10、Seasonal variations in precipitation and long-term changes in precipitation patterns, such as droughts, have a big impact on hydropower production.
对
错
答案:
11、Petroleum and natural gas beneath the ocean floor are also considered a form of ocean energy.
对
错
答案:
12、Hydropower systems build pressure either by containing the water behind a dam, or within a pipe that runs down a hill. The weight of the water behind the dam or in the pipe creates pressure at the bottom. More height creates more pressure, and more pressure means we can get more power from the flow of water.
对
错
答案:
13、The 1973 oil embargo and 1979 energy crisis caused a reorganization of energy policies around the world and brought renewed attention to developing solar technologies.
