why do we need to use alternative 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.
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.
