why do we need alternative energy sources

There is a current global need for clean and renewable energy sources. Fossil fuels are non-renewable and require finite resources, which are dwindling because of high cost and environmentally damaging retrieval techniques. So, the need for cheap and obtainable resources is greatly needed. An efficient and more feasible alternative option is solar energy. Solar energy is a more practical type of energy due to its plentiful availability; it is derived directly from the sun. In 2010, renewable energy only provided 8 percent of the total energy consumption in the United States. Many people probably wonder: if renewable energy is so beneficial, why don t we consume more of it? The answer to the question is that many of the renewable energy sources are more expensive and more difficult to retrieve. Thus, because of these limitations, the consumption of fossil fuels has grown to an exorbitant rate. Although there has been an increased effort to incorporate solar power, these efforts have not alternated its use by a great amount; less than 1 percent of the electricity in the United States is supplied by solar power. In the United States, California utilizes the most solar power. After it was denied funding by the federal government, a solar company, received private funding from Bank of America Merrill Lynch.

This project will ultimately provide solar electric panels on roofs for over 120,000 military housing units and spans over the next five years. The bank has agreed to lend up to $350 million for the implementation of the project. The new undertaking is a huge leap for the solar industry. Renewable energy sources, specifically solar power, can be extremely practical as alternatives to damaging carbon-intensive fuels. Original article by Jill Dolowich for MNN
Energy sources like crude oil, coal and natural gas are essential for various purposes. Most of our day-to-day activities will come to a standstill if these energy sources are not available to us. There is an ongoing debate whether we require alternative energy sources or if there are enough energy sources like crude oil and natural gas to meet the growing demands of individuals and industries throughout the world. Due to the growing population there will be more demand for energy resources in future. It is believed that fossil fuels such as natural gas and crude oil will get depleted after few decades. Though technology has paved way for oil companies to extract oil from unproved oil reserves there is no guarantee that the future demand for these fossil fuels can be met.

Fossil fuels like natural gas and crude oil are non renewable as well as harmful to the environment upon burning. Hence the need for an alternative energy source arises. Fossil fuels are naturally occurring energy sources, which are formed from dead plants, and creatures buried under soil some millions of years ago. At the current rate of consumption it's difficult to extract newly formed fossil fuels as the rate of production of such fossil fuels is extremely slow which will take hundreds of years. Alternative energy source like solar power is natural and renewable. Fossil fuels contribute largely to global warming which has become a major environmental issue. Solar and wind energy will not get depleted unlike crude oil and they can be used repeatedly. People are slowly switching to alternative energy sources due to its varied advantages over the limited stock of non-renewable energy sources. Few countries have already realized the need for using energy sources like wind and solar power. It's not possible for the entire world to be fully dependent upon fossil fuels.

Using alternative energy sources will help in saving fossil fuels like crude oil and natural gas for emergency use in future. Investing money in energy sources like solar power will help consumers in the long run. The price of crude oil is skyrocketing and the underdeveloped countries find it difficult to consume such energy sources. Many countries are in need of crude oil for transportation, which proves expensive. An alternative energy, which is less expensive and less harmful to the environment, will be a boon to underdeveloped countries. Many countries have started investing their money in researching and inventing different energy sources. Apart from polluting the environment, fossil fuels are harmful to living things like plants and animals. They are responsible for sudden climatic changes and greenhouse effect. Fossil fuels are non renewable, hazardous to environment and they are also becoming expensive. Thus this paves way for using alternative energy sources for cooking and heating as they are renewable, environmental friendly and easily available. We can save our environment from getting polluted to a large extent by exploiting environmental friendly energy sources.
