Wind Power VS Solar Power

Solar Power

The electricity can be produced by using solar energy with the help of solar panels. It is a great environment friendly choice to produce electricity. The solar panels used in solar power system take light and turn into electricity with the help of photoelectric effect. The solar panels are being used since 18th century. Solar power is an efficient and reliable way of producing electricity as it is renewable source of energy. There is no emission of carbon dioxide and other toxin gases in the solar power therefore it is an environment friendly system. The installation of solar power system is very simple.

Wind Power

The electricity can also be produced by using wind power. It is also cost efficient and environment friendly way of producing electricity. The turbines are used in wind power which can spin with magnet to produce electricity. If there is high speed wind then more electricity can be produced. The good thing about wind power system is that it can work all the day and night. It is very effective way to produce electricity with the blow of wind. You can be able to operate wind power even in the polar region. It will emit no harmful wastes and toxin gases like carbon dioxide.

Whatever method is used, both these ways are very important for us as both these are renewable sources of energy.

Solid and Liquid Biofuel

Biofuel is an efficient way or producing electricity to meet the energy requirements. There are many raw materials used in biofuels to produce electricity. There are solid as well as liquid fuels available to use in the bio-fuels.

Liquid Biofuel

Biodiesel and bioalcohol are the liquid forms used in the biofuels to produce electricity. The liquid biofuels are used to run cars. There is no emission of harmful gases with liquid biofuels like bio-alcohol into the air which can cause global warming and destruction in ozone layer. Biodiesel and ethanol are the great options for liquid biofuels. These biofuels are produced by transforming oils and fats into biodiesel and sodium hydroxide and ethanol or methanol is mixed in it. This fuel can be used to run automobiles like cars and trucks. The liquid biofuels are normally taken from the plant sources.

Solid Biofuels

Wood chips, sawdust and grass clipping are some solids which can be used as an alternative energy sources in which mass of substance is compressed. Pellet form is the result when these materials are compressed which can burn for heat. There can be emission of pollutants and toxin gases into the air by these solid forms. But still these solids are great way to meet the energy requirements.

The main purpose of these biofuels is to reduce the impact of energy on environment. The liquid biofuels can be good option as it is environment friendly and cost efficient as well.

What is Tidal Power?

Tidal power is also known as tidal energy. The tidal power can be obtained by capturing energy created by the movement of water in ocean currents and tides. Kinetic energy is the main source of tidal power which is known as tidal energy. The potential energy is the other way through tidal power generates electricity due to difference of low and high tide height which is referred as head. There are turbines used in kinetic tidal power to produce renewable energy.

The energy is extracted to convert it into electricity by using tidal power. These tides are generated due to gravitational force between moon and earth. The water is caught when it is at high tide and then stored. Dam is constructed to create a tidal plant which is called barrage. There is device used in these barrages called sluice with which tide allowing is opened to come in at high tide. The turbine is attached to generator from where water rushed past.

The tidal power is being used in many countries since 18th century. It can produce lots of energy. The electricity produced by tidal power is affordable, efficient and abundant. It is a free source of energy and there is no greenhouse and other toxin gases emission. It is reliable source of energy and it is inexpensive to maintain as well. The tides can be predicted very easily because of gravitational force, frequency of tides and their direction. Tidal power is a great way of generating electricity.
