2021-10-20 Dying Polluting Gas Wells Are Making Company Rich

This is shameful. 60% of the 44 gas wells ware leaking methane into the air. This Diversified Energy owns tens of thousands of dying wells that are polluting the environment and spewing greenhouse gases. And they’re still trying to acquire more. 15 min. video. https://youtu.be/6c-WCg2Y7sE

2021-10-19 Renewables Leading Source US Electricity By 2030 – EIA

According to the EIA, renewables will be the leading source of US electricity by 2030. The EIA says 42%, but they have been too conservative in their estimates in the past. We (the whole world) must be much farther away from fossil fuels by 2030, especially coal. Coal power plants must be gone as soon

2021-10-07 Nuclear Fusion Confusion Explained

Sabine explains the difference between nuclear fusion reaction’s Qplasma and Qtotal. There is a huge difference between the two. To put out more power than is needed to keep the reactor running, the output of the fusion reaction must be greater than Qtotal. At the rate the experiments are progressing, it will be many decades

2021-09-05 Blue Hydrogen Is Greenwashing By Big Oil

At 13:00 Dave talked about how problematic green hydrogen is, and at 13:30 he said why not just use the electricity directly for the home. Herein is the whole problem: the solar and wind electricity is generated at times when it is not needed and not generated when it is needed. So we still have

2021-07-28 Concentrated Solar Power, Solar PV

Thread from FB << Michael Burns Concentrated Solar Power (CSP) is a totally different technology, which has a lot of operational advantages over PV, but still many disadvantages compared to other generation types. Functionally, CSP is simply thermal energy storage, so like a battery, when it’s “charged”, it can be included in the short term

2021-07-28 CO2 Capture And Sequestration

Utilities should capture CO2 directly from power plants, while it’s still highly concentrated. The following is from: https://19january2017snapshot.epa.gov/climatechange/carbon-dioxide-capture-and-sequestration-overview_.html << As estimated in the U.S. Inventory of Greenhouse Gas Emissions and Sinks, more than 40% of CO2 emissions in the United States are from electric power generation. >> << According to the Greenhouse Gas Reporting Program,

2021-07-19 Carbon Capture And Sequestration, DAC

This long article is about carbon capture and sequestration with a section on DAC direct air capture. We must reduce the 410 parts per million in our atmosphere! Quote: << Lackner says DAC is a good fit with renewable energy. If a natural gas power plant is off because of low demand, so is any

2021-07-15 Hydrogen Turbines Vs. Lithium Ion

The cost of green hydrogen must come down or else the gas turbines must be used as a peaker plant during the time when high demand causes electricity price to spike. As the percentage of renewables increases, this may happen more often. But that will cost consumers. https://www.pv-magazine.com/2021/07/14/hydrogen-fired-gas-turbines-vs-lithium-ion-storage/
