Green energy refers to any source of energy or power, which is sustainable and less harmful to the environment and human health. The other names for green energy are sustainable or renewable energy. This type of energy is derived from sources that do not affect nature. These sources meet environmental needs without causing any depletion. Many countries in the world if not all are looking to this energy as a climate savior. The world is facing global warming and measures have to be put in place to ensure that further damage is controlled.
There are a number of sources of green energy. Some of these are biofuels, wind power, solar power, wave power, tidal power and geothermal power. All these are environmental friendly. The main difference is in regards to cost. Some of the sources are quite expensive to run and maintain while others are relatively affordable. What is for sure is that these technologies improve energy efficiency. They are split into three main generations. Geothermal/hydroelectric sources represent the first generation. Wind/solar energy sources represent the second generation. Last but not least, solar thermal and biogas gasification are the third generation technologies.
The use of green energy is gaining popularity across the world. More and more organizations are adopting this type of energy due to its environmental friendly nature. Families and households have not been left behind. Some of the renewable energy sources are very expensive as compared to the non-renewable. The cost element to be precise is what drives most homes into the use of green energy.
Biogas is a relevant and perfect example of green energy that many households have tapped into their homes. It emanates from bacteria during the degradation process of organic material. This process is anaerobic which means that there are no air conditions involved. The anaerobic bacteria decompose all organic matter in the absence of oxygen to produce a gas. The use of biogas brings with it a wide range of benefits to both the environment and the people using it. It assists in the production of heat, electricity and light. In addition to this, it also helps in improving hygienic conditions through the reduction of flies, pathogens and worm eggs.
The other green energy that most households are adopting is solar power. There is no doubt that solar power is most affordable and easy to maintain source of energy. It is very natural coming from the sun and as long as individuals have solar panels, they are good to go. The good and most amazing attribute about solar power is its incredible versatility. It has the ability to power a wide range of inventions such as water heaters, cars, satellites, buildings and fountains among others.
It is very important that households adopt green sources of energy. This ensures that the environment is not depleted and that the lives of human beings also remain safe and healthy. The future looks bright if renewable energy is put into practice. The problems facing the environment can all be alleviated if the world at large makes good use of green energy.
