The various types of energy are the base materials that power is generated. They are transformed into secondary forms like fuels and electricity, which are then transmitted through various channels to supply the energy that powers our lives, factories, homes and cars. Energy sources are categorized as renewable and non-renewable.
Renewable (or clean energy) is energy that is generated from sources of natural resources that are continuously replenished. Examples include solar power, wind power, water power and geothermal energy. Fossil Fuels (coal natural gas and oil) are not renewable since they form more slowly than we do.
Solar energy can be harnessed on a single rooftop or in large solar power plants. Solar energy can be converted to photovoltaic energy, which generates electricity directly. Water can be used for the production of hydropower or for energy generated by tides and waves. Geothermal energy is sourced from reservoirs of hot water underground. Bioenergy is derived from organic resources like woody plants, animal dung and human waste.
In addition to being environmentally friendly In addition, renewable energy is usually cheaper than fossil fuels. The challenge, however, is that renewable energy requires a huge infrastructure to harvest and transport the energy, which could result in web link complicated trade-offs for environmental, social and economic reasons. Nevertheless, the development of these technologies continues to grow and are making inroads against the more traditional fossil fuels. Renewables could even be cheaper in the long term than oil and coal.
