The main sources of energy in the past included petroleum and coal. With the sharp increase in energy prices, the depletion of non-renewable energy sources, and the increase in greenhouse gases affecting global warming, the future of using alternative “green” energy sources looks bright. Governments around the world are feeling the pressure of consumers’ demands for alternative renewable energy sources that will not harm the environment.
Wind energy is one of the ways to produce “green energy” that is becoming popular all over the world. Wind turbines are used to generate energy. Wind turbines can be placed wherever there is sufficient amount of wind. The more wind turbines installed, the more electricity will be produced.
Solar energy is one of the alternative energy sources that is expected to see an increase in its use in the future. This type of energy makes use of the sun for energy and heat. Solar panels harness the sun’s energy without polluting the planet and the atmosphere. Solar generators provide electricity. Solar panels are installed on the roofs of residential and commercial buildings. In the future, larger solar panels will be built that can power hundreds of thousands of homes, solar energy requires no other source of energy to operate and is pollution-free. Sunlight can be harnessed as usable heat or converted into electricity using photovoltaic cells, solar panels, or by using synchronized mirrors called heliostats that track the sun as it moves. Methods have also been developed for using solar energy to replace a gas-powered engine by heating hydrogen gas in a tank. There were positive results when the generator was turned on.
Hydropower is another alternative energy source with proven results. The flowing water powers the turbines that produce the energy. The energy created depends on the strength and power of the flow of water because the rapidly flowing water drives the mechanisms that help in the production of electricity. The current is then sent through a transformer where the electricity is transmitted through power lines. This is an environmentally friendly form of energy and in the future, it is expected that more hydroelectric power stations will be established where there is a suitable water source.
Existing technologies of new renewable green energy sources, especially solar and wind energy, have proven very promising for the future. In addition, geothermal energy, which is heat energy extracted from the earth to generate steam to power generators that produce electricity, is another potentially great source of energy in the future. There is also a lot of research and development in the field of nuclear fission. The salinization of estuarine water as an energy source is another potential source of alternative energy because many experts suggest that it will take millions of years before there is any impact. Nuclear fusion and artificial photosynthesis are two other energy technologies that are currently being researched as potential energy sources in the future.
Many traditional sources of energy are becoming unsustainable, making new, greener energy sources the wave of the future. Many companies, “green” entrepreneurs, and governments are investing in the future of the planet and its inhabitants by investing in alternative renewable energy sources. Investing in “green” energy means a future of lower energy costs and a greener sustainable environment.
