Sustainable Future

Renewable energy refers to energy sources that are naturally replenishing such as the sun and the wind, which not exhausted over time. This energy used for generating electricity, heating water, and cooling, as well as for transportation. According to a REN21 report of 2016, global renewable energy consumption accelerated by 19.2 in 2014 and 23.7 in 2015. In 2015, investments in sustainable development carried in annual worth of $286 billion majored in biofuels, solar, wind, and hydroelectric power. Unlike renewable energy, this type of energy is found in limited quantities because it takes millions of years to form and regenerate from finite fossil fuels.
