This electric motorcycle brand sold out in just 2 hours, netting $7 million

This EV could be usable in many parts of the world.

At $1,200, I might even want one.

The more I think about it if we go solar one day I'm not sure I want to tie into the grid with the system.

Today you can only get 1.5¢/kWh from TVA for your generated PV power. When Congress passed a law mandating utilities provide gridtie for PV power they set the minimum to be the "audited incremental cost of generation". This is a genuinely fair price. The utility should not have to pay you more for a kWh than they themselves can generate. It doesn't pay for the construction of the generating plant, it only pays for the fuel, labor, and maintenance of having to generate 1 more kWh than not generating the 1 kWh.

Alabama Power has bastardized the Congressional act to the point there is almost no PV installations in the southern 4/5ths of Alabama. Charges the homeowner $5/month per kW of peak PV generating capacity.

Alabama Power fees on solar challenged

The Alabama Public Service Commission will hold a Nov. 21 hearing on a challenge to the fees charged by Alabama Power.

Newer information details the price Alabama Power pays for generated power but makes no mention of the above monthly fee. With perfect weather one has to be paid at least 3¢/kWh to break even on the $5/kWh fee. Assume full output for 5 hours/day for 30 days.

To PV off-grid one must amortize the cost of battery storage. Batteries wear and must eventually be replaced. The cost of battery wear storing electricity is greater than the incremental cost to generate using traditional coal or nuclear means.

10-15 years ago the same intellectual doofuses who convinced leftist PSC Czars to impose "net metering" parity gridtie on utilities also theorized they had jurisdiction over your EV battery to commandeer for "load shedding". That they should be allowed to freely use your EV for temporary storage. Fortunately that got nixed.

Today the rolling blackouts in Texas and California are due to many mistakes and total lack of understanding of commerce and economics. They think their wishes will magically work if the opponents are silenced. With net metering parity pricing there is no benefit to having one's own energy storage. Quite the contrary, storage is a penalty because you can "store" in the grid for free. Sell your power to the utility for the same price you can buy it back tonight. The utility gets nothing for the cost of building the grid or maintaining the grid. They get nothing to pay the interest on capital, nothing to pay for the generating plants.

A few months ago I had two guys that was out replacing a security lamp that quit burning. They were not pro on home owners selling power back to the grid. What I'm talking about would not be cost-effective but it would just make sure that I could charge an EV even if the grid was down and maybe just quit using the grid for everything depending how much money I put into the system.

I had not realized how much work had been put into electric planes.

Falling renewables costs undercut new and some existing coal plants - study

Coal is going away in time because most people can count. Most people will start buying EVs because they can count.

What Sam Walton did to lower our cost of goods Elon Musk is doing for the cost of transportation and energy.

Today a Tesla Model Y sells for about $3K more than a similarly equipped Model 3. The cost to produce a Model Y in TX is to cost $10K less than to produce the same trimmed Model 3 in CA today.

Just the new rear Giga casting for the Model Y reduces the parts count by 370 pieces.

Just as car makers are dropping the gas engine for the better and less expensive electric motor since Tesla showed them how to do it. They will move to the Giga Castings frames technology just like other rocket makers will start landing and reusing first stage rockets.

People will be buying EVs because they can count. People will be using renewable energy not to Save the Planet but to Save a Buck because people can COUNT.
