The cost of large scale land-based wind power is now the least expensive electricity, and it is the fastest growing. And the cost of solar PV is coming down quickly. We will be seeing water based wind power come online, and tidal and wave power, too. Solar heat systems are also being built. Hydro has some room for growth in any existing dam site. Biogas can be made at each and every sewage treatment plant and large farm, and this can be stored and burned in existing gas plants.

Solar PV is a great fit for the grid - the peak demand is for A/C during the day, and the base load plants *need* to have a predictable use during the night. Wind tends to blow more at night, and when wind turbines are spread out and well planned, then they provide a predictable amount of power. Tidal power is *very* predictable, and wave power is consistent most of the time. We can have more storage, too - elevated hydro, underground compressed air, and thermal storage for solar heat plants are already here. Grid scale batteries are going to be here soon - and when there are enough EV's, their batteries can be used as part of a "smarter" grid to buffer energy.

Renewable energy gets less expensive over time, both because they (mostly) burn no fuel, and they have no pollution, and their "supply" is going to be here as long as the earth exists. So yes, I think that electricity costs will stay level, or even go down over time.

If we can avoid the extreme costs of climate change - yes, we can save money and save our shared home at the same time.

Edit: all the money we pay for electricity stays in our local economy. As we all know, we now are paying 1 Billion dollars or more PER DAY for foreign oil.

EV's are local economic power...
