2021-03-08 Billions And Billions of kWh and Money??

I went here to see what the EIA says about this BS and the figures he gave look totally fake.,0,1&fuel=vtvv&geo=g&sec=g&linechart=ELEC.GEN.ALL-US-99.M~ELEC.GEN.COW-US-99.M~ELEC.GEN.NG-US-99.M~ELEC.GEN.NUC-US-99.M~ELEC.GEN.HYC-US-99.M~ELEC.GEN.WND-US-99.M~ELEC.GEN.TSN-US-99.M&columnchart=ELEC.GEN.ALL-US-99.M~ELEC.GEN.COW-US-99.M~ELEC.GEN.NG-US-99.M~ELEC.GEN.NUC-US-99.M~ELEC.GEN.HYC-US-99.M~ELEC.GEN.WND-US-99.M&map=ELEC.GEN.ALL-US-99.M&freq=M&start=200101&end=202012&chartindexed=0&ctype=linechart&ltype=pin&rtype=s&pin=&rse=0&maptype=0 I got this from a comment in << motofunk ยท 5 hours ago It’s a huge change coming. To replace the 6,630,136,986 kWh’s the US generates daily from fossil fuels we will need

2021-03-07 Micro Hydro Systems With No Dams

Comment from Just Have A Think #142 – 2021-03-07 I have to remind Dave that these microhydro systems do have downsides. The 24/7 requirement is getting more difficult because large hydro projects upstream can make the river highly variable, and rivers often slow to a trickle or dry up after the spring rains / snow

2021-02-28 3 kW Solar + LiFe Battery For Under $3000

This is the kind of setup I would like to have. I would use it to run my heat pump / air conditioner and maybe a few other things like the microwave oven. And it would be used for charging my EV when it’s at home. The two solar PV panels are 800 watts total.

2021-02-25 Cal. Electric Customers Getting Screwed

This new TOU (time of use) charges per kWh are costing us more, but also we’re having to pay for things that were not our fault but the fault of SCE, PG&E and SDG&E.

2021-02-18 Q: Is 100% solar wind and batteries (or storage) possible by 2030?

Q: “Is 100% solar wind and batteries (or storage) possible by 2030?” A: Not possible if left to the IOUs (investor owned utilities). They are regulated and if left to their own choices they will do exactly what they did in Texas — they will do the minimum necessary to maximize profits while charging the

2021-01-27 Report On Monopolized Energy Sector

A few big corporations are monopolizing the energy sector, and causing the US to lag behind when it comes to clean renewables, and maximizing profits at the expense of the consumer.

2021-01-19 Battery Storage Disrupts Natural Gas Plants

The Hornsdale Battery Storage has made a big disruption in the market for electricity in South Australia. Since it can supply electricity almost instantaneously it outcompetes the gas turbine generating plants even though it is a much smaller percent of the total electric supply. The South Australia state has a large amount of renewables –

2020-12-18 Alternator Charges Battery

This setup just charges the battery as long as the resistor is connected to the field coil. There is no regulation of the charge and it can overcharge the battery. To properly regulate the charging, the alternator should have a regulator instead of the resistor. The regulator will shut off the charging when the battery

2020-12-06 Structurally Integrated Batteries

Also left a comment on JHAT Dec 6. Structural batteries and also integration with motors is a fascinating subject. But it suffers from the same problems that the integrated circuits suffered from over the last several decades. Before the integrated circuits could be highly integrated, the optimal structure had to be determined. Things like 8,

2020-09-28 Tesla, Sonnen, And Other Home Battery Systems

Matt Ferrell has the text to his YouTube video about the Tesla Powerwall, Sonnen, etc. and a link to the video. The Tesla Powerwall and others cost about $10,000 installed. The systems may allow you to run your home from the battery when there is a power outage on the grid. Solar PV panels will
