What is meant by Green Energy

What is meant by green energy? Green energy, also known as renewable energy, refers to energy derived from naturally replenishing sources that have minimal impact on the environment. Unlike fossil fuels, which release harmful greenhouse gases and contribute to climate change, green energy sources produce little to no emissions during their operation. This environmentally friendly approach to energy generation is crucial in mitigating the effects of global warming and preserving our planet for future generations.

Various forms of green energy are available, each harnessing a specific natural resource. Solar energy, for instance, is generated by capturing sunlight and converting it into electricity through photovoltaic cells. According to the International Energy Agency (IEA), solar energy accounted for approximately 2.7% of global electricity generation in 2021 and is projected to rise significantly in the coming years.

Wind energy is another prominent green energy source that utilizes the power of wind turbines to generate electricity. In 2021, wind power contributed around 7.2% of the world's electricity generation, and this figure is anticipated to grow steadily as technology advancements continue.

Hydropower, one of the oldest and most reliable forms of renewable energy, harnesses the kinetic energy of moving water to produce electricity. In 2021, hydropower constituted approximately 16.1% of global electricity generation, making it a significant contributor to the world's energy mix.

The transition to green energy is not only driven by its environmental benefits but also by economic factors. The cost of renewable energy technologies has been declining rapidly over the years, making them increasingly competitive with conventional energy sources. According to the Renewables 2021 Global Status Report, the levelized cost of electricity from solar photovoltaic and wind power has fallen by about 85% and 56%, respectively, since 2010.
