The different types of energy are the base materials that power is generated. They are transformed into secondary forms like fuels and electricity. They are then transported through various channels to supply the energy that powers our homes, industries, and cars. Energy sources can be classified as renewable or not.
Renewable (or clean) energy is generated from natural resources that are constantly replenished. Examples include wind power, solar power, water power, and geothermal energy. Fossil fuels (coal oil, natural gas) are considered non-renewable because they form https://leonardogiombini.it/2019/02/14/interessante-articolo-sui-biocarburanti/ at a much lower rate than what we consume from them, which means they will eventually end up being depleted.
Solar energy can be harnessed by one rooftop or in large solar power plants. It can also be converted into photovoltaic solar energy which generates electricity directly. Water can be harnessed for hydropower, or be utilized for tide and wave energy. Geothermal energy is generated by underground reservoirs that contain hot water. Bioenergy is derived from organic sources like woody crops, animal dung, and human waste.
In addition to being environmentally friendly, renewable energy is often cheaper than fossil fuels. The problem is that renewable energy requires massive infrastructure to harvest and transport the energy, and can lead to complicated trade-offs for economic, social and environmental reasons. The development of these technologies continues to expand, and they are progressing against traditional fuels. In the future renewables could prove to be more affordable than oil and coal.
