Today I'll be talking about a fuel for which demand should grow rather than reduce. The fuel that I'm talking about is often called a 'hidden fuel', or the 'first fuel'. Yes, you've guessed it, today's topic is energy efficiency.
As part of the Paris Agreement, we need to limit global warming to well below 2 degrees Celsius, which means that we need to reach zero net emissions from the second half of this century.
Energy efficiency means to either perform the same activity with less energy input or accomplish more activity with the same amount of energy input. Either way, you achieve more with each unit of energy consumed.
Think of energy efficiency as the cheapest and cleanest fuel you can use, as it is measured and valued as the quantity of energy you do not use. The higher the price you pay for your electricity, the greater the value to being more productive with your energy input.
Apart from saving you money, improving energy efficiency means that your renewable energy needs will be smaller, which can make your journey to net-zero emissions less expensive. It also reduces the environmental impact of manufacturing, transporting, and installing renewables.
