商品簡介
Currently, the world's electricity generation relies heavily on coal, oil and natural gas. Fossil fuels are non-renewable; they are based on limited resources that are gradually running out. In contrast, renewable energies such as wind and solar energy are constantly being replaced and never run out. Most renewable energies come from the sun, either directly or indirectly. Sunlight, or solar energy, can be used directly to heat and illuminate homes and other buildings, to generate electricity, to heat water, solar heaters, and a variety of economic and industrial applications. Pleasant heat also causes the wind to blow; The same energy received by wind turbines; Then the winds and the heat of the sun cause the water to evaporate. When this water vapor is turned into rain or snow and is directed from streams to rivers and waterways, its energy can be taken and its hydroelectric power can be used. Along with rain and snow, sunlight causes Let plants grow, the substance that makes those plants, we know as living mass or biomass. Biomass can be used to generate electricity, transport fuels or chemicals.
