Do you believe in global warming? Climate changes? These are big problems that we must address. There are some people out there that don't believe in any of this. Weather you do or not we must start exploring green energy. Why? Do you really think that the oil and gas will last forever? I know it wont. We need to look into all green power ideas that we have.
Wind power, Tidal power, Solar power, Geothermal and Hydro power are all options that we can explore. But,no power source is entirely impact-free. All energy sources require energy and give rise to some degree of pollution from manufacture of the technology.
Those not satisfied with the third-party grid approach to green energy via the power grid can install their own locally-based renewable energy system. Renewable energy electrical systems from solar to wind to even local hydro-power in some cases, are some of the many types of renewable energy systems available locally. Additionally, for those interested in heating and cooling their dwelling via renewable energy, geothermal heat pump systems that tap the constant temperature of the earth, which is around 7 to 15 degrees Celsius a few feet underground, are an option and save money over conventional natural gas and petroleum-fueled heat approaches.
Green power is becoming more affordable also. Solar panels and geo-thermal units are becoming more mainstream now and over time as oil and gas prices raise these approaches will become more attractive.
