We sloppily turn on the light and leave them on anytime. But energy will not be available forever. There is limited supply of energy resources on our planet. Renewable and nonrenewable are two categories based on their perishing ability. There is a rough estimate that we have energy for next half century or few more years only. The energy demand of the rising population cannot be met easily, unless we think of renewable energy sources. The pros and cons of switching to renewable source of energy are discussed here. Mainly hydro, geothermal, wind, solar, biomass and ocean resources are used for generating renewable energy. You don’t actually contribute to the pollution while using these renewable energy resources. The rising global warming scare and greenhouse effects have made the environmentalists think about lesser fossil fuel use and more renewable energy.
Solar power is preferred as it is user friendly. The setup can easily be assembled in buildings and living spaces. There is limitation of light in the solar energy usage. Wind energy is without doubt widely used among the other sources of energy. Renewable wind energy relies on the strong currents of wind. Large wind turbines are setup on open plots and farms, though there are some cons like noise, gigantic structure construction and hazard to birds.
Geothermal energy is one novel mode of power generation. The ground and earth’s core heat is used to create energy. It is highly specific to the sites and may only be used in certain areas. Hydroelectricity is generated throughout the world. It is one of the most reliable forms of generating renewable energy. There are some downsides like pollution, wildlife threat and flooding. More research is ongoing on the biomass energy. Even ocean energy resources are being explored. More emphasis is laid on the renewable form of energy sources. Gradually success will be achieved to incorporate these eco-friendly methods in our routine use.
