why do we need renewable energy sources
For thousands of years we have relied on burning fossil fuels to generate energy, but in todayвs world using oil, gas and coal for our energy needs is becoming a problem. Climate change is one of the greatest environmental challenges that we have ever faced, and the main cause behind it is our dependence on fossil fuels. Burning coal, petroleum and other fossil fuels is the primary means by which we produce electricity, but it also leads to heavy concentrations of pollutants in our air and water. Another problem with using fossil fuels to generate energy is that there is not a limitless amount available. For the past couple of centuries, we have come to rely more and more on the worldвs supply of fossil fuels, and that supply is fast running out. As the demand for fossil fuels has increased, the cost of using them has also increased and each year we find ourselves with larger and larger energy bills.
The answer to all of these problems? Renewable energy. Energy such as solar energy, wind energy and water power is generated from natural energy sources and unlike fossil fuels, these sources of energy never run out. With a much lower impact on the environment, using renewable energy helps to protect our planet by significantly reducing the amount of carbon emissions that we produce. By using renewable energy sources, we also reduce our dependence on fossil fuel gas and oil reserves, which means that we can avoid the rising cost of energy bills and improve our energy security. In order to preserve our planet, our wallets and our energy sources we all need to be involved in switching to renewable energy sources and making or homes more energy efficient.
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
