One step towards green & clean energy

Sustainable energy is energy produced and used in such a way that it "meets the needs of the present without compromising the ability of future generations to meet their own needs." It is similar to the concepts of green energy and clean energy in its consideration of environmental impacts, however formal definitions of sustainable energy also include economic and social impacts.

Coal, oil, and natural gas remain the primary global energy sources even as renewables have begun rapidly increasing.

The energy transition to meet the world's needs for electricity, heating, cooling, and power for transport in a sustainable way is widely considered to be one of the greatest challenges facing humanity in the 21st century. Production and consumption of energy emits over 70% of human-caused greenhouse gas emissions. Worldwide, nearly a billion people lack access to electricity, and around 3 billion rely on smoky fuels such as wood, charcoal or animal dung to cook. These and fossil fuels are a major contributor to air pollution, which causes an estimated 7 million deaths per year.

In general, renewable energy sources such as solar, wind, and hydroelectric energy are widely considered to be sustainable. However, aspects of some renewable energy projects, such as the clearing of forests for the production of biofuels, can lead to similar worse environmental damage than using fossil fuel energy. Nuclear power is a low-carbon source and has a safety record comparable to wind and solar, but radioactive waste and the risk of major accidents are disadvantages of this technology.

Moderate amounts of wind and solar energy, which are intermittent energy sources, can be integrated into the electrical grid without additional infrastructure such as grid energy storage and demand-response measures. These sources generated 8.5% of worldwide electricity in 2019, a share that has grown rapidly.

Answer 2

Answer:

There are more than 7 billion people on the planet, and each year, we dump more that one billion tons worth of waste. More than 30% of coral reefs have been destroyed, and over nine million tons of plastic are dumped into our oceans on a year to year basis. With these statistics in mind, it is no wonder many people are looking for ways to become eco-friendly. More and more businesses are making appropriate moves to become more environmentally-friendly. While a lot of home owners want to make similar moves to help the planet, they often find themselves in situations where they are unsure what the first step is.
