There is not a day that passes that the world doesn’t produce carbon dioxide and release it into the atmosphere. The sad part of this is that carbon dioxide will remain there for over one hundred years.
As the world’s carbon dioxide usage continues, it is increasing the temperature of the planet, and that is responsible for the “Global Warming Effect”. One way to combat this is to increase the use of alternative energy sources by replacing current technologies with those that do not produce carbon dioxide.
As world governments continue to embrace alternative energies sources, it is estimated that by 2050, a third of the world’s energy will come as a result of wind, solar and other resources that are deemed renewable.
As we continue that journey towards becoming a world that doesn’t produce carbon dioxide in our never-ending thirst for power we take a look at those that will be responsible for achieving that goal.
Wind power is far more affordable in comparison to current energies sources. First, it is pollution-free but does have some limitations. The main limitation is the number of windmills that are needed to produce large amounts of energy. They are seen by many as unattractive and an eye-sore to the environment and cannot be installed everywhere and are based on the flow of wind to be effective. They are also seen as costly to install, operate and maintain.
Solar power is the most popular alternative energy source, and the one that has the best reputation as being affordable, both to governments, industry and personal use. The benefit they offer is the amount of carbon dioxide that is saved from being released into the atmosphere. Governments that invest in solar also will prevent the need to burn coal and solar doesn’t produce smog, acid rain or other pollutants.
Biomass and biodiesel are the most commonly used renewable energy sources. They are the opposite of fossil fuels that are created through geological processes. Biomass is the creation of biofuels from anaerobic and agriculture digestion. This includes ethanol from corn, a fuel that burns much cleaner than fossil fuels.
Tidal power is somewhat new in the renewable energy field. It makes use of the oceans waves and tides to spin underwater turbines that create energy. One of the largest tidal power facilities in the world is in France. It operates much like a hydroelectric plant to produce electricity that is then connected to the power grid.
Geothermal is another renewable energy source that more governments are embracing. The best known for this resource is Iceland as they have a higher degree of geothermal activity under their surface. Geothermal uses the natural heat trapped within the earth to create steam and then use that steam to spin turbines that can be used for electricity or to heat homes.
