Humans have relied on conventional sources of energy since the time immemorial- be it the coal, wood, gas or oil. We have used and over used these resources in order to fulfil our greedy ambitions and robbed the future generations of their rightful access and claim to these resources. Increased demands to meet the needs of over 7.5 billion humans has resulted in unparalleled levels of pollution in air, land, wetlands, water bodies along with depletion of forests. According to Global Footprint Network, by August 1 2018,humans consumed more resources than Earth could regenerate for the year. In simpler terms, we are now using the resources of close to 1.5 earths in a year.
Renewable energy often provides energy in four important areas: electricity generation, air and water heating /cooling, transportation, and rural (off-grid) energy services.
- Green house gases do not get emitted by the use of renewable energysources. This makes it the cleanest form of energy & use of it o prevents environmental degradation.
- As the source is infinite like winds , sun light , tides etc. , it is very much sustainable & there is no threat for the next generation..
