TESLA POWERWALL 2.0 FOR STABILIZING DISTRIBUTION GRIDS
Tesla markets a wall-hung, 14 kWh Powerwall 2.0 battery unit, with lithium-ion cells made by Panasonic, either in Japan or Nevada. The unit is designed for daily charging and discharging.
The turnkey cost of the unit = $6,200, factory FOB + S & H + Contractor markup of about 10 percent + Misc. hardware + Installation by 2 electricians, say 16 hours @ $60/h = $8,200, or $586/kWh of battery…Continue

The turnkey capital cost of battery systems has been decreasing the past few years. The below table has turnkey capital costs/kWh of some 2016 and 2017 projects. Subsidies, such as cash grants, discounts, investment tax credit, ITC, and 5-year accelerated depreciation, which serve to reduce the cost/kWh, were ignored.

The EU and US have declared, “Burning wood is CO2-neutral”. East Europe and the US Southeast still have significant areas with forests. Starting about 2005, major parts of these forests have been harvested by means of clear-cutting. In 2016, about 6.5 million metric ton of wood pellets will be shipped from the US Southeast to Europe for co-firing in coal-fired power plants. The EU authorities in Brussels have declared these coal plants in compliance with EU CO2/kWh standards, because biomass…Continue

Vermont Senator Bray is being pressured by the starry-eyed, "90% RE by 2050" folks (the latest trend is 100% RE, a nice round number). Many of those RE folks, a.k.a. "stakeholders" are looking to cash in as much federal and state subsidy money as possible, as quickly as possible. They use the mantra of fighting climate change, global warming and job creation. Other RE folks likely have near-zero experience in the analysis of energy systems.
Accordingly, Senator Bray, eager to…Continue

For the past 200 years, we have multiplied from 1.0 billion in 1800 to 7.4 billion in 2016, and will multiply to a likely 9.5 billion by 2050.
Most of them have lived the good life, courtesy of our fossil fuel inheritance. Transitioning to biofuels is like having to get a real job and work for the annual yield, year after year; a yield subject to the vagaries of the weather.
No more freebees from nature that were just lying around for millions of years waiting…Continue

Vermont’s proposed carbon tax is as described in this URL. Proponents claim the carbon tax would be 90% “revenue neutral”, i.e., mostly returned to the economy likely in convoluted ways, via inefficient, ponderous, government programs in the form of “targeted” tax credits, subsidies, rebates, grants, etc. There would be taxpayer and employer tax rebates, but amounts and eligibility were not specified.…Continue
