The Different Types of Energy
Energy is generated from a variety of types of energy. They are transformed into secondary forms, such as fuels and electricity, which are then transported through various channels to provide the power that runs our lives, factories, homes and cars. Energy sources are categorized as renewable and non-renewable.
Renewable (or clean energy) is energy that is produced from natural resources that are constantly replenished. Examples include wind, solar and geothermal. Fossil fuels (coal oil and natural gas) are not renewable since they form slower than we utilize them.
Solar energy can be harnessed by a single rooftop or in large solar power plants. It can also be transformed into photovoltaic solar energy, which generates electricity directly. Water can be harnessed to create hydropower, or be tapped for the energy of waves and tides. Geothermal power is generated from underground reservoirs of hot water. Bioenergy comes from many organic sources, like woody crops as well as dung from livestock and human wastes.
In addition to being eco-friendly, renewable energy is often less Related Site expensive than fossil fuels. The problem is that renewables require massive infrastructure to harvest and transport the energy, and can lead to difficult trade-offs due to economic, social and environmental reasons. The development of these technologies is continuing to grow and they are making strides against the more conventional fuels. In the long run renewable energy may be more cost-effective than coal and oil.
