Renewable Energy is the key to our global energy requirements in the long term, as we deplete our source of uranium as well as fossil fuels or maybe the price tag of these fuels climbs up for political or economic reasons, the cost of renewable energy can be much more competitive. Using present technologies, most ocean energy is not cost-effective in comparison to many other renewable energy sources however the marine remains one of the necessary potential source of energy for the future. Both renewable and non-renewable sources of energy are widely used to produce electricity, power vehicles, and also offer heating, cooling, and light. Renewable Energy is energy created from resources that happen to be regenerative - or renewable - which means they cannot be depleted. These natural resources are safe for the planet of ours and Nikola Tesla produce electricity without the dangerous emissions and pollutants associated with fossil-fuels. As the this industry expands, the knowledge of these support industries has been tapped to offer the support and infrastructure necessary for the development of unlimited energy production internationally. The reason behind the enormous growth is global organizations are searching for green or renewable resource technologies as well as organizations to invest in, fund, acquire, license or perhaps strategically partner with. Top priority is given to technologies which are patented or commercial goods with present or perhaps near term revenue streams. Renewable energy systems encompass a diverse, diverse array of technologies, and also the current condition of these can differ considerably. Several technologies are already mature also economically cut-throat. Globally we realize that using renewable energy has got the potential to provide us with cleaner air, a much more diverse energy portfolio, and a reduced amount of dependence on international fossil fuels. Presently renewable resources accounts for only 3.4 percent of complete global power generation. The International Energy Agency recently granted a report estimating that to be able to reduce green house gas emissions 50 % by 2050, global investment in unlimited energy, energy efficiency and carbon sequestration will need to achieve roughly US $45 trillion dollars by that date. It is expected that sixty % of all our energy is going to come from renewable resources by the entire year 2070. The sooner we employ the attitude which today is better than tomorrow, the greater the chance to elevate this figure to 80 %. Renewable energy is sustainable energy that comes from the natural environment. Renewable energy, or perhaps green energy, is power coming from renewable energy like the sun, wind, non-chemical material and hydro-electric dams (biomass). These resources are constantly replenished by nature and are a cleaner source of energy.
