Renewable or regenerative energy – is the energy from sources that, according to human scale, are inexhaustible. The basic principle of the use of renewable energy consists in extracted from it constantly occurring in the environment and processes providing for the technical application. Renewable energy comes from natural resources such as sunlight, water flows, wind, tides and geothermal heat, which are renewable.
Renewable energy resources exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security, climate change mitigation, and economic benefits.
Types of NON CONVENTIONAL ENERGY SOURCES:
- Wind power is harnessed by setting up a windmill which is used for pumping water, grinding grain and generating electricity.
- Sun is the source of all energy on the earth. It is most abundant, inexhaustible and universal source of energy.
- Geo-thermal energy is the heat of the earth’s interior.
- Biomass refers to all plant material and animal excreta when considered as an energy source. Some important kinds of biomass are inferior wood, urban waste, bagasse, farm animal and human waste.
Importance of non-conventional sources of energy:
- They are abundant in nature.
- These are renewable resources.
- Non-conventional sources of energy are pollution-free and eco-friendly.
