New advances in wind-turbine design enable turbines to operate at lower wind speeds to convert wind ________ electricity more efficiently.

Solar panels, wind turbines, hydro power and geothermal energy and hydrocarbons (natural gas or coal) can all be used to produce hydrogen (a primary energy).

Nuclear power is the use of nuclear reactions that release nuclear energy to generate _____, which most frequently is then used in steam turbines to produce electricity in a nuclear power plant.

The way of digester mixing: ( ). A: The digester gas is compressed and injected into the liquid through lances or diffusers. B: Mechanical mixers, usually slow speed turbines, create liquid motion inside the digester. C: A combination of above three ways. D: The liquid contents are recirculated by pumping them from one location to another.

In Scotland, for example, wind turbines provide enough [color=#ff3853]electricity[/color] to power 95 percent of homes. A: n. 电力；电流 B: n. 马车；火车车厢；运费 C: n. 松树；松木 未知类型：{'label': 'source', 'content': '2018年英语二阅读理解Part\xa0A\xa0Text\xa02', 'isMemberControl': 0, 'type': 181}
