Massachusetts uses 389 billion cu ft of natural gas and 89 million barrels of petroleum and only 16.9% of homes use electricity for heating(often the inefficient induction variety).

Renewable sources becoming cheaper is great news for the world a few decades from now when that changes but this year is going to be a cold one for anyone trying to survive on a budget.

Most people won't be able to install a multi-thousand dollar new heat pump furnace that is entirely fueled by pre-negotiated renewable electricity providers. Even the ones with heat pumps would get hit hard by increasing energy demand on the grid(which still heavily used gas and oil for energy production).
