Many people think the search for cleaner energy leads only to renewable resources like sun, wind and water.But it also leads to a fossil fuel.Natural gas is considered the cleanest of the fossil fuels, the fuel created by plant and animal remains over millions of years.Burning it releases ...
Instead, e-fuels instead are generated by using decarbonised power sources, such as wind, solar or wave. They can come in gas or liquid form and by advocates, they are considered better for the environment, because the carbon released during application was captured during production. What is...
What is the order of the water cycle? What fuels evaporation in the ocean? Where does some water from the water cycle collect underground? What are Milankovitch cycles? How are clouds formed in the water cycle? Where does the water cycle end?
答案38.C 39.C 40.D 41.B 解析 38.根据文中“most of the energy comes from coal,oil and gas,we call them fossil fuels"可知大部分来自化 石燃料。 39.根据文中“to light our houses,to warm up the water”可知太阳能可以用来照亮房子和加热水。 40.根据文中"such energy does not pollute the...

It also says that because the combination of improved renewables availability – including the likes of hydro, wind and solar — is coupled with much higher nuclear generation, fossil fuels have been pushed down the merit order most of the time, meaning gas plants are moving further away from ...
Solar power collects energy from the sun using solar panels and converts that solar energy into electricity. Solar power advantages and disadvantages Besides its abundant availability, solar power has a much lower environmental impact orcarbon footprintthan fossil fuels, in both its production and use...
We use fossil fuels as one source, the oil and gas most machines use. We can use wind turbines to gain energy from the winds, and even utilize the flow of water to produce energy for our society. Some of these sources are renewable, like the wind energy or energy gained from the ...
