2022-06-16 Nanogrid Uses Hydrogen Storage

I really like this all-in-one solar plus storage system which has both batteries and green hydrogen generation, storage and fuel cells. It’s expensive but everything is integrated into one package. https://electrek.co/2022/06/16/check-out-this-solar-green-hydrogen-mobile-nanogrid-with-a-level-2-ev-charger/

2022-06-15 Gas Turbine Is Running On 100% Hydrogen

Gas turbine runs on 100% pure hydrogen. The skeptics are constantly complaining about how the wind and solar renewables “will never” be able to give the grid dispatchable power. Well, as long as gas turbines can run on hydrogen, they can still be used as generation as long as they burn green hydrogen. However there

2022-06-14 Calif Reached 100% Renewable Electricity

Originally an EarthDay.org article. They made 3 points. They said, <<California must still rely on fossil fuels to meet its energy demands.>> The peak energy demands can be reduced by using a ‘smart grid’ where the grid has some control over the heavier demands. One example is residential HVAC and hot water. These can be

2022-06-10 Burning FFs Accounts For 87% Global CO2

Burning fossil fuels accounts for 87% of global CO2 emissions. The cost of solar has fallen more quickly than experts predicted. https://cleantechnica.com/2022/06/08/just-the-facts-the-cost-of-solar-has-fallen-more-quickly-than-experts-predicted/

2022-05-30 Examining Big Oil’s Climate Pledges

The house oversight committee examins Big Oil’s climate pledges. They need to hold the fossil fuel industry’s feet to the fire and make them pay penalties for failing to meet climate pledge promises and commitments. https://oversight.house.gov/legislation/hearings/fueling-the-climate-crisis-examining-big-oils-climate-pledges

2022-05-27 Wind Turbine End-of-life Waste

Comparison of wind turbine waste. There really is no comparison – coal power plants generate hundreds of times more fly ash waste than wind turbines, and fly ash is toxic! Compared to coal, wind turbine waste is insignificant! Wind turbine blade waste generates 0.163 kg per MWh over a 20 year period. A coal power

2022-05-07 Nuclear Energy Is Not The Answer – 7 Reasons

https://eu.boell.org/en/2021/04/26/7-reasons-why-nuclear-energy-not-answer-solve-climate-change The 7 reasons why nuclear energy is not the answer to solve climate change Analysis New nuclear power costs about 5 times more than onshore wind power per kWh. Nuclear takes 5 to 17 years longer between planning and operation and produces on average 23 times the emissions per unit electricity generated. In addition,

2022-05-06 Methane Is Much Worse Than CO2

The world has a much more dangerous greenhouse gas than CO2 – it’s methane, also known as natural gas. And huge amounts are locked up in the environment, and may be released by global warming. Biofuelspk said, “… natural gas which is 84 times worse for climate change compared to CO2.” I’ve read the numbers
