Some Vermont renewable energy proponents have a fanciful notion of “Making Vermont Energy Independent”. Some legislators repeat it as part of their RE rhetoric and talking points. There is an organization “Energy Independent Vermont”, sponsored by VPIRG that espouses this independence movement, along with a tax on carbon. One such carbon tax envisions raising $520 million per year by 2026.

Hawaii has increased its PV solar systems in recent years. The energy is generated mostly between 10 am and 2 pm, whereas peak demand is later in the evening. Battery systems have been installed to shift a part of the solar energy to peak hours.
Here is a description of a PV solar/Battery system combo.
In Kauai, Hawaii, there is a 52 MWh of battery…Continue

This article shows a method of calculating the CO2 associated with electricity consumption of any state in New England. In this case it was applied to Vermont. At the end of the article is a list of references.
The Energy Information Agency, EIA, calculates CO2 emissions based on in-state fossil fuel electricity generation; Vermont has very little of such generation, i.e., according to the EIA Vermont has a small quantity of CO2 emissions relating to electricity. It is…Continue
WIND, SOLAR AND HYDRO ELECTRICITY COSTS
If massive build-outs of heavily subsidized wind and solar were to occur (at great expense and environmental damage), which would have upstream CO2 emissions, electric grids would gradually become “cleaner”, i.e., have less CO2/kWh.
That approach would take decades, plus the variable, intermittent, grid disturbing, electricity from:
1) Large-scale, ridge-line wind…Continue
This article deals with the energy from source to electrical energy user. The complete pathway must be used to enable evaluation of one energy pathway versus another. First some definitions:
- Source energy is the energy taken from coal mines, oil and gas wells, and forests for conversion to electricity and heat.
- Primary energy = source energy - energy used for exploration, extraction, processing and transport of fuels (coal, oil, gas, biofuels, wastes, etc.) to…Continue

As part of the quest of having energy sources that produce near-zero CO2 emissions, energy systems analysts have looked at hydrogen as one such source. They see hydrogen as a possible fuel for transportation.
In California, the hydrogen economy movement has received support, in the form of subsidies and demonstration projects, from the state government and environmental groups, often supported and financed by prominent Hollywood actors.
