Renewable Energy; Solar, Hydro and Wind Power

Solar, hydro and wind power have all proven that they can produce electricity, but the problem that arises is the economic sustainability of each method and their feasibility in various locations. If we are to phase out burning of fossil fuels we need a reliable and economically viable renewable energy source that can sustain the needs of an ever-growing worldwide population.

Hydro power plants were known to produce a great deal of electricity; however the requirements of these plants made it quite impossible to be used in many geographical locations. In this type of plants you’ll need massive amounts of current water to keep turbines from spinning, so it has been adapted in various countries which are blessed with scenic and powerful waterfalls, but even there it turned out that these power plants are largely just supplemental to grid produced electricity.

Wind Turbines are not reliable because we cannot predict if there would be enough wind to keep them spinning and the huge areas of land required to house them is unavailable in many countries. Though these plants are used to power a fraction of some cities today, it can also be considered as only a supplemental energy source worldwide.

Probably the most viable technology today is the harnessing of solar energy; although the suns energy isn’t available the entire day, it has proven itself to be a highly effective generator of large amounts of clean renewable power around the world, even in cooler European climates. The very flexible technology of solar PV panels which allows it to be scaled to small residential use through to very large commercial soalr power parks has been the key to its success,……though wind and hydro power plants produce a great deal of energy they need to be in colossal proportions to be viable. Solar energy produced via Solar Photovoltaic panels still requires a large amount of roof space but it is efficient enough to be truly viable replacement for at least 20% of current “dirty” energy production methods worldwide

All of these alternative renewable energy innovations are beneficial in the long run; if we can have all of them working at the same time in every country in the world we just might cut off the need for burning of fossil fuels before our Earths resources run out!
