Renewable energy mainly includes solar energy, wind energy, hydropower, biomass energy, geothermal energy and ocean energy.
1. Solar Energy: The sun is our most powerful source of energy. Sunlight, or solar energy, can be used to heat, light, and cool homes and other buildings, as well as to generate electricity, heat water, and various industrial processes. Solar energy harvesting technologies have evolved in recent years, including water-heated roof pipes, photovoltaic cells and mirror arrays. Panels installed on roofs will not affect the ecology of the ground, but large solar panels installed on the ground could compete with wildlife for habitat.
2. Wind Power: Wind is the movement of air that occurs when warm air rises and cold air rushes over it.quick to replace it. For centuries, wind power has been used to sail ships and power windmills that grind grain. Today, wind energy is captured by wind turbines and used to produce electricity. Questions periodically arise about where wind turbines should be installed because of the impact they can have on migratory birds and bats.
3. Hydropower: Water is a renewable resource that is continually replenished through global cycles of evaporation and precipitation. The heat from the sun causes water in lakes and oceans to evaporate and form clouds. The water then falls back to Earth as rain or snow, flows into rivers and streams, and returns to the ocean. Moving water can be used to drive water wheels, thereby driving mechanical processes.
4. Biomass Energy: Biomass has always been an important source of energy. Wood remains the most common biomass energy source, but other biomass energy sources include food crops, grasses and other plants, agricultural and forestry wastes and residues, organic components of waste municipal and industrial, and even methane harvested from community landfill gases. Biomass can be used to generate electricity and as a transportation fuel, or to make products that would otherwise require the use of non-renewable fossil fuels.
5. Geothermal energy: Geothermal energy can be extracted from deep underground reservoirs by drilling, or from other geothermal reservoirs closer to the surface. This application is increasingly used to offset heating and cooling costs in residential buildings.els and commercial. Heat from the Earth's interior creates steam and hot water, which can be used in generators and electricity production, or for other purposes such as home heating and energy production. industrial electricity.
6. Ocean Energy: The ocean provides several forms of renewable energy, each powered by different forces. Wave and tidal energy can be used to generate electricity, and ocean thermal energy – heat stored in seawater – can also be converted into electricity.
