Summary: Discusses the importance of alternate sources of energy. Details the different types of alternate energy sources currently available.
Alternate sources of energy include solar,wind,tidal and thermal energy.In solar energy energy from the sun is converted into other usable forms of energy using solar panels,mirrors etc.Wind energy uses the energy of moving air;tidal enegy uses the energy of the movement of water during high and low tides and thermal eneregy uses the energy stored in the earth in various forms like, hot springs, geysers etc.
Eventhough a lot of research has gone into it the main reason why we are still dependant on fossil fuels is due to the high cost of such technologies and in the case of certain cases, to the lack of these technologies.
There is also problems due to the lack of efficiency of such systems and the lack of awareness about such systems.
It is important that people know that these alternate sources can lead to much more cleaner,cheaper and safer energy sources.The day is not far when these sources will herald a new revolution in energy production.

Essay about Solar Power: The Future of Energy
1431 Words6 Pages
I am certain that all have heard of the terms green house gases, fossil fuels, and global warming. Have you ever questioned what will happen if nothing is done about the environmental problems facing the world today? What if I answer you that, we can merely use the power from the sun to power up our entire planet without the use of harmful energy sources, which affect our atmosphere? The power from the sun is what we call solar power. Solar power is the energy that comes from the sun as light and heat energy, and then it is later converted into electrical energy through solar panels (Nelson, 2008). This kind of power is completely free, right? Why should we put a lot of expense on other sources of energy, when there is a complete free…show more content…
If we choose to switch to solar energy in future, it will greatly save our environment because, it does not pollute our air and it is reasonably efficient. It will help reduce global warming, and thus a future green environment with no pollution from fossil fuels, and other conventional sources of energy. To add on that, it will also help in conserving our remaining fossil fuels so that it may not run out in the coming 100-500 years, as it has been predicted. In addition, solar energy operational costs are manageable. It is free from monthly charges compared to conventional sources of energy. Solar energy does not require raw materials such as oil and coal, and once the panels are built, there will be no monthly charges. In addition, the prices of fossil fuels are increasing day by day, and this means conventional energy will be very expensive. Solar energy will remain the most capable world’s future power supply because, it is cost effective once the plants are built, and there will be no transport costs like for conventional energy sources. Therefore, solar energy is cost-effective, and will help in future energy supply, as the maintenance cost is affordable, as long as they are installed properly, and are working efficiently ( Hans, 2012). Furthermore, with the improvement and advancement of technology, it will increase its efficiency, and cost of production thus, making it more cost effective and the world’s best
