Renewable energy is the energy which is generated by using natural resources like Sunlight, air, tides, etc which can be naturally replenished. Some examples of renewable energy are biofuels, biomass, Geothermal, Hydro power, Tidal power, Solar power, Wave power, Wind power, etc.
In the year 2006, about 18% of global final energy consumption came from renewable energy. Renewable energy projects are suited for both large scale industries and for small off grid applications in rural and remote areas. Kenya has the highest ownership of solar power systems sold per year with the figure of 30,000.
Biomass is also about renewable energy. It refers to dead biological material which can be used as fuel or for industrial production. It also means plant matter grown to generate electricity. Biomass also includes biodegradable wastes that can be burnt as fuel.
When the garbage is decomposed, the methane which is produced by it, is captured in pipes and then burned to produce electricity. Biomass is available abundant in Earth.
We can grow industrial biomass from numerous types of plants which includes hemp, miscanthus, switch grass, corn, sugarcane, willow, sorghum, and from a variety of tree species like palm oil and eucalyptus.
Tidal power is also known as tidal energy. It is a form of hydro power that converts the energy of tides into electricity. Tidal power is not used much in the world, but it has much potential for future.
Tidal power is the only form of energy which we get from the motion of the Earth and Moon system and sometimes from Earth and Sun system. For the generation of tides, the tidal forces which are produced by the Sun- Moon, in combination to Earth's rotation are responsible.
The Earth's tides are caused by the gravitational interaction with the Sun and the Moon, and the Earth's rotation, and due to this, tidal power is generally inexhaustible and is known as a renewable energy source.
The solar power is a form of renewable energy. Renewable energy is the energy which is generated by use of natural resources which are naturally replenished. Humans have used solar energy from ancient times, to satisfy his various needs.
