One of the first things we all need to do if we're not already is switch to renewable electricity in our homes because it cuts our dependence on fossil fuels, reduces emissions, and it supports that vital transition to a greener grid."

This year, I'm really happy to say we're around 17 and a half, 18 degrees. Just watch your bills drop when you turn that thermostat down."
