How much co2 will you save with solar panels?
Going green is a big part of investing in solar panels, and while the investment benefits can be considerable, there are environmental perks as well. This calculation gives you a good idea of how much Co2 you will save by using solar.
Co2 Emissions by Power Plants – The National Grid PLC estimated that commercial power stations produce an average of 392 grams of Co2 per KwH of electricity. This is an average because coal plants produce much more while others like nuclear produce less.
Solar Co2 Emissions – Solar panels produce an average of 88 grams of Co2 per KwH from manufacture until they are defunct. This includes everything, from acquiring raw materials to production to transport and installation.
Essentially, solar panels produce 77.56% less C02 per KwH of electricity.
Installing solar panels can be a great decision for your home, for the environment, and for your savings. In fact, with an average return of 4.8% over 25 years, solar panels offer a return comparable to most ISA and investment accounts. Hopefully you can use our free calculator to determine if solar is a good fit for you.
