Renewable energy resources

Renewable energy resources.

What is Renewable Energy?. Renewabl energy sources are those energy resources which can be replenished. The supply of these resources is unlimited and they can be renewed..

What are the types of Renewable Energy Resources?.

What is Solar Energy?. Solar energy is provided by the sun. We receive solar energy in the form of solar radiation. It is widely available, renewable, and a clean form of energy..

Advantages of Solar Energy. Solar energy is renewable and sustainable. Solar energy has proved to be helpful for the people living in rural regions. Solar energy provides a very low level of emission. Solar panels need low maintenance..

Disadvantages of Solar Energy. The initial investment,or the cost, of setting up the solar panels are high. Solar energy is available only during the day. The set-up and installation of solar panels need large areas..

What is Wind Energy?. Wind energy is a pollution-free and an inexhaustible source of energy. It is simple to generate electricity from the movement of wind..

Advantages of Wind Energy. Wind energy is a cheap source of energy. Wind energy is a clean source of energy and does not pollute air. Wind energy is sustainable. The windmill can be built on the existing farms..

Disadvantages of Wind Energy. The technology of wind energy needs a higher initial investment. The turbine blades while rotating cause noise pollution. Winds are unpredictable and uncertain..

What is Hydroelectricity?. Hydroelectricity is turbine power derived from the energy of falling water. The water is stored in the reservoirs that are built in the hilly and mountainous regions. When the stored water is released from the reservoir,it flows through a turbine causing it to spin. This in turn activates a generator which produces electricity..

Advantages of Hydroelectricity. Hydroelectricity offers a reliable and efficient source of energy. After the initial construction cost of the dams, the operation and maintenance cost are low..

Disadvantages of Hydroelectricity. The initial investment cost is very high. Many people are displayed to build reservoirs..

What is Tidal Energy?. Ocean tides can be used to generate electricity. Tides are predictable, therefore, a reliable source of energy. Tides are caused by the gravitational pull exerted by the sun and the moon and rotation of the earth..

Advantages of Tidal Energy. Tidal energy has no greenhouse gas emissions. Tidal energy has a low environmental impact. Tidal energy is a very predictable source of energy..

Disadvantages of Tidal Energy. The amount of electricity generated by tidal energy is very small. The tidal energy production involves specific sites to produce electricity..
