Advantages of Wind Power

The use of wind power can reduce greenhouse effect and global warming by reducing CO2 and other toxin gases. It is a renewable source of energy and there is no emission of pollution with it. Wind energy is absolutely free therefore cost of this electricity is also very low. The turbines for wind power can take very little space and can provide more space for agricultural and environmental use. You can find turbines in different sizes. You can combine wind power with solar power as well in order to produce more electricity. It is cost effective way of electricity with which you can produce lots of energy and you just need to install turbines in remote and mountainous areas.

Disadvantages of Wind Power

There are some disadvantages of wind power as well. You might not sure about the exact production of electricity with wind power so it is unreliable. The wind turbines used to produce electricity can last not more than a year. These turbines can produce lots of noise. The wind exposure is also quite variable in many areas which are also a disadvantage. You can store wind energy only with the help of battery. There can be higher initial investment as compared to fossil fuel systems. You have to gather plenty of data about the speed, frequency and direction of wind and then place turbines according to this data. You might need to change these turbines with the change in direction of wind.

Advantages of Tidal Power

The tidal power has many advantages. Tidal power is free once dam and plant is set up. There are no greenhouse gases or other wasters produced by it. The electricity produced by tidal power is reliable and facilities of tidal power are inexpensive to maintain as well. The electricity produced by tidal power is very cheap as compared to other sources. There is plenty of water on earth surface therefore there will be no shortage of electricity produced by tidal power. There will be no worry in producing electricity once dam is built.

Disadvantages of Tidal Power

The biggest disadvantage of tidal power is that there is lots of money required for tidal power projects. The dams can not be built on saltwater environments because of there corrosive nature. The tidal power projects require high tidal range as well. There can be effects of tidal power station on plants and animals in estuaries. There is suitable sight required by wave energy and tidal power and waves are not feasible always. The maintenance of tidal power station is also a difficult task and it requires lots of money. The tidal turbines will depend on tides and sometimes you will produce no electricity if there are no tides.

These are some advantages and disadvantages of tidal power.

It is a free source of energy as tides are generated naturally. The energy will go on releasing as long as there is gravitational pull from moon. There are no adverse effects of tidal energy on environment. There will be no emission of unhealthy greenhouse gases by creating and using this type of energy. There will be no wastes produced by this energy. There will no large money require for the production of electricity with tidal energy.

It is reliable, affordable and abundant source of producing electricity. There can be high electricity production if there is higher density of water. It is renewable source of energy which produces electricity efficiently. The tidal energy can be obtained by building barrages at high tidal range areas. The tidal energy power can contribute to electrical system effectively because tidal energy is predictable due to gravity, tidal currents and lunar cycle.

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.

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.
