Energy is a critical issue for our environment. We rely on energy resources that are finite; they will run out sooner or later, although there are methods to extend their life. The question is, how will we collect, use, and efficiently utilize the energy resources which are presently available?
The major source of energy in the United States is coal. Coal has been in use for a long time. It was used both as a power source and as a fuel. The problem with this energy source is that it pollutes the air, and it contributes to the destruction of our natural resources.
Natural gas and oil are also limited. In addition, the earthworm and the microbial decay of these sources is very slow. Solar energy is plentiful, but the sun is a moving object, and it is not always visible in places where there are no solar panels. To collect this energy, you have to place them in a location where the sun is visible. Then, there would need to be storage batteries for storing the electricity produced.
Another source of energy that is used today is biomass. Biomass can be used as fuel and as organic fertilizer. It is not widely used, because of its limited availability. Carbon dioxide from burning fossil fuels is one of the major contributors to global warming. Carbon dioxide is one of the energy resources that are being used up by renewable energy.
Wind energy is another resource being used up by energy resources. Although wind generators have increased in development over the past twenty years, they still do not meet the energy needs of many people. It is used to produce electricity for wind farms. Unfortunately, the wind generators need to cover a lot of land. Also, they require subsidies from the federal government.
Biofuels are also being used as an alternative to fossil fuels. This includes ethanol and biodiesel. Both of these are derived from organic materials and are therefore considered as sustainable energy resources. Ethanol is made from starch grains and biogas produced by bacteria in the digestive tract of corn.
Solar energy is also becoming an alternative for renewable energy. Photovoltaic cells can create electricity using the sun’s energy. Solar energy panels have become a part of homes across America. The technology for solar energy is still developing and more research needs to be done in this area. Although, there are now many solar companies that are offering various forms of residential, commercial and industrial solar energy. Many people who use solar power are able to reduce or eliminate their power bills by making some changes to their home or business.
The evolution and future growth of renewable energy will continue for years to come. The United States and other developed countries will become more dependent on this type of energy as fossil fuels begin to be depleted. The developing world will also become an increasingly important source for renewable energy. If we, as a planet, do not take care of the problems of the planet today, the problems of tomorrow will only become larger as we continue to burn fossil fuels and destroy the environment.
The development of renewable energy will continue to increase in popularity globally. The major benefits of renewable energy are that it will save money and prevent global warming. Fossil fuels emit carbon dioxide, which is leading to global warming. Bio-fuels like ethanol, bio petrol and biodiesel are better alternatives than fossil fuels for reducing carbon emissions and are expected to become much more popular in the coming years. As more people start to use these sources, the cost of energy will decrease leading to more sustainable sources of energy.
The evolution and future growth of renewable energy will also create economic growth in developing countries. Today, many people in the United States and Europe pay for energy sources that they could easily obtain free. It will only be a matter of time before other countries follow suit. There will always be a need for energy, and developing countries can provide it for those who need it.
The problem is currently finding enough energy sources. We currently use over seven billion barrels of oil each day, and this figure is growing by the day. We have many oil reserves around the world, but most of them are being depleted at an alarming rate. The growth of renewable energy will allow us to discover new sources of energy and stop the decline of our resources.
