We need energetic processes which produce as little pollution as possible. We need sustainable development that will allow us to live within limits of what the Earth is able to provide and what is required for a healthy biosphere. We need a green economy that aims to reduce environmental risks and ecological scarcities. We need a socially responsible low carbon economy that conserves and protects the Earths ecosystems.
Renewables not only offer environmental benefits like climate change mitigation, they also afford energy security and a wealth of economic advantages. Renewable energy is a huge and growing source of jobs. The number of clean energy employment opportunities dwarfs the number of jobs in the fossil fuel industry. There are also $160 trillion dollars worth of savings associated with climate action and massive risks associated with inaction.
Reducing our need for energy is also very important way to reduce adverse environmental impacts associated with power generation. Efficient energy (aka energy efficiency) helps to maintain the environment by protecting the air and preventing the change of climate. It also helps by reducing the emission from dirty power plants. Energy efficiency is also tied to the creation of smart grids which manage energy distribution. However locally generated renewable energy combined with energy storage systems may be the most forward looking way of addressing energy demand.
Hybrid Renewable Energy Sources (HRES) is also playing a role in meeting our energy needs, particularly in remote ares. HRES involves combining of the two renewable energy sources with the aim of providing higher energy efficiency along with the greater energy output and efficiency.
