Alternative Energy for Future

Nowadays the most common energy resources come from Fossil Fuel, which according to research it shows that more of 85% of all energy that is consumed in the United States. It takes millions of years for the Fossil Fuel to actually develop and ready to be used, and the main concern of Fossil Fuel is that it cannot be consumed over and over again or reused. Through this analysis it can be assumed that because it takes millions of years for the fossil fuel to develop, and we came up with two assumptions that would lead the innovation of producing energy using different resources. The first assumption is that there is more fossil fuel that is used rather than what is provided or reserved by the nature. This act …show more content…

There are two different types of thermal energy used, passive and active form. Passive solar heating does not require any equipments because the heat because it enters the building independently. On the other hand, active solar heating needs a medium to absorb and store solar radiation. One example of an active solar heating is energy storage system. Other than that, solar thermal power plant indirectly produces electric power when heat of the solar collected is used to heat a fluid; this method could transfer a system to produce steam. Solar thermal energy works almost the same as creating energy but actually it is by converting energy using the sun’s radiation.

Besides passive and active benefits of using solar energy, it also has less damage and fewer side effects to the environment since it does not produce any pollution. However, there are costs in terms of producing solar cells. Many scientists aware of the negative impacts that photovoltaic cells production has, it is because toxic metal such as mercury, lead, and cadmium are used during the process of manufacturing solar cell. It definitely increases the issue of global warming. However we all know that all good things must have a trade off, where in this case the amount of good that we receive is more than the cost that we produce. Thus it is a good thing for the society.
