Energy is generated from a variety of types of energy. They are transformed into secondary forms like fuels and electricity, and then transmitted through various channels in order to supply the energy that powers our houses, industries, and automobiles. Energy sources are categorized as renewable and non-renewable.

Renewable (or clean) energy comes from natural resources that are constantly replenished. Examples include wind power, solar power, water power and geothermal energy. Fossil fuels (coal natural gas and oil) are not renewable because they are formed much slower than the energy we use.

Solar energy can either be harnessed in large solar power plants, or on one roof. Solar energy can be converted into photovoltaic energy, which generates electricity directly. Water can be harnessed for hydropower, or be used to generate wave and tidal energy. Geothermal power comes from underground reservoirs of hot waters. Bioenergy can be obtained from organic sources such as woody crops, animal dung and human waste.

The problem is that renewables require massive infrastructure to harvest and transport the energy, which can create difficult trade-offs for economic, social and environmental reasons. Nevertheless, the development of these technologies continues to grow and they are gaining ground against more traditional fossil fuels. Renewable energy could be more affordable in the long term than oil and coal.
