Overall, the evidence is consistent that pro-renewable and efficiency policies work, lowering total energy use and the role of fossil fuels in providing that energy. But the policies still don't have a large-enough impact that they can consistently offset emissions associated with economic growth

Tax carbon emissions and methane emissions.. it really is that simple. We're not willing to do it because it "hurts lower income people".

Taxing carbon makes renewable energy sources more lucrative both at the power plant level or at the home level where people would have more incentive to buy solar panels and battery banks to balance peak/off-peak power. It means more justification for getting rid of your car and using public transportation, or riding a bike, or buying a car with better fuel economy, or buying an electric. It means properly insulating your home or moving into a smaller place because it makes sense with energy prices going up. It means buying fewer "things" because those things will see their prices go up because they use energy to make. It means using road materials that don't generate so many carbon emissions. It means eating less meat. Etc.
