White House cautiously opens the door to study blocking sun’s rays to slow global warming
A Biden administration report required by Congress outlines research options for a last-ditch effort to slow the heating of the planet. But the White House says it's not changing its climate strategy.

The price per kWh will be 2 or 3 times the cost of charging at home, for fast charging, even with no home solar power generation and storage, with it home charging could be free or much cheaper than the power rates.
Every large city is surrounded by suburbs, bedroom communities and industrial parks that can provide plenty of local power and eventually store it in home battery banks and plugged in EVs, meaning less power will need to be imported or generated by utilities. Smart grids and smart electrical panels will be required along with economical home storage to make it happen, but much of a city's energy requirements can be generated locally from the urban sprawl surrounding it.

Rooftop Solar Panel Capacity Will Be Overtaken by EV Chargers in 2023
The expected growth in electric vehicle charger capacity is thanks to federal incentives, a report says.

The grid economic model will need to be reimagined along with getting smarter, both at grid scale and at the service entrance to the home, with EVs there will be more incentive to have rooftop solar, especially when it will be integrated into roofing shingles and tiles. People who produce and store energy will obviously get the best deal for grid service, but everybody will need to pay a basic membership fee to the utility. If you own an EV just covering your garage with solar panels could dramatically reduce your transportation costs. It distributes not just energy production and storage for a portion of the grid, but the capital costs too. In some places they are mandating EV plug ins for new construction, and it might not be long before solar roofs are mandated for new construction or replacement too.
Who pays? We all do one way or another, from grid owners to homeowners looking to cut energy costs or even become independent. In some cases, government mandates, subsidies, grants and rebates will be used to spur change. Solar is now the cheapest form of energy generation, but we need energy storage and long distance HVDC to make it work on a large scale. Up in our latitudes wind generation will be an important factor too, but further south the more solar makes sense. Here in NS there are gov grants and incentives to convert from oil heating and resistive electric to heat pumps for instance.

The truth about mineral resources.
5,793 views Jul 2, 2023
Will batteries for hundreds of millions of future electric vehicles rob the planet of all its precious minerals? And what about all the minerals and materials for billions of wind turbines and solar panels? Can our planet really cope with the transition away from fossil fuels and will that transition really be 'sustainable'?

Can The U.S. Power Grid Handle The EV Boom?
162,944 views Jul 1, 2023 #CNBC
The EV revolution could put a major strain on the nation’s electric grid, an aging system built for a world that runs on fossil fuels. To upgrade the grid to meet growing electricity demand, the U.S. needs to build a massive amount of new transmission and distribution lines to connect new renewable energy resources to population centers. But there are major regulatory hurdles to grid infrastructure buildout, and the government is not investing near the amount that analysts say the nation needs in order to meet its electrification targets.

The more wind, solar, HVDC lines, battery storage and smarter grid they have, the less likely those coal plants will be fired up.

It's one Devil or another, the lesser of two evils. Climate change is hard on deserts too, with flash floods, prolonged drought and extreme weather events like heatwaves. 40C might be a dry desert heat, but it is still 40C!Locally, solar is becoming a serious eco and health issue.

The more solar is integrated into roof tops with solar shingles and roofing tiles, the less solar farms that will be required, that goes for energy storage too. I believe the rooftops of urban sprawl and bodies of water can do much to reduce the demand for such installations and water can cool solar panels too. Speaking of cooling, they have coatings that can block or reflect much of the infrared radiation while allowing the usable light through, thus lowering the temps of the panel and prolonging its life while increasing its productivity.Locally, solar is becoming a serious eco and health issue.
