Energy comes from various forms of energy. They are converted into secondary forms such as fuels and electricity, and then transmitted through various channels in order to generate the power that powers our homes, industries, and automobiles. Energy sources can be classified as renewable or non-renewable.

Renewable (or clean energy) is energy that https://leonardogiombini.it/2019/03/01/le-biomasse-i-processi-termochimici is produced from sources of natural resources which are continually replenished. Examples include solar, wind and geothermal. Fossil fuels (coal, oil and natural gas) are considered non-renewable as they are formed at a slower rate than the energy we use them, which means that they will eventually end up being depleted.

Solar energy can be harnessed in large solar power plants, or on one roof. Solar energy can be converted into photovoltaic power, which creates electricity directly. Water can be harnessed to create hydropower, or be utilized for waves and tidal energy. Geothermal power is derived from underground reservoirs of hot water. Bioenergy comes from a variety of organic sources, such as woody crops as well as dung from livestock and human wastes.

In addition to being environmentally friendly In addition, renewable energy tends to be less expensive than fossil fuels. Renewables are expensive and require a large infrastructure to harvest and distribute the energy. This can lead to complicated trade-offs in environmental, social, and economic factors. However, the advancement of these technologies continues to increase and are making strides against more traditional fossil fuels. In the future renewable energy may be more affordable than oil and coal.
