Melissa Hortman was only 55 years old. She had a lot more to do. It is so bitter and so sad that her life was taken - assassinated for fighting for what she believed in. It will now be up to us to carry on these fights.

The Republican Finance draft is a head fake and farce. It increases energy costs. Period. The quick phaseout for solar and wind alone will make energy more expensive, make it harder to compete with China, and kill thousands upon thousands of jobs across the country, mostly in Republican districts.

Wow, the House Republican tax bill would increase gas prices. By a lot. Up to 37¢ per gallon! New numbers published by CAP show how ending clean energy investment props up demand for fossil fuels, raises prices, and makes households pay an extra $400b over the next decade to Big Oil and Gas.
Excerpt from the Center for American Progress piece published at https://www.americanprogress.org/article/the-house-republican-plan-to-increase-gas-and-electricity-prices/


The House Republican bill would:

Raise gasoline prices by 25 cents to 37 cents per gallon by 2035 as demand for oil increases due to the termination of federal electric vehicle affordability programs, fuel economy standards, and tailpipe emission standards.

Repeal the financial support for buying new, used, or leased electric vehicles, which would keep between 22 million and 40 million more gasoline-powered cars and trucks on the road through 2035, as roughly one-third of families who would have tried to switch to an electric vehicle can no longer afford one.

Increase electricity prices for households and industry as roughly two-thirds of the wind and solar that was previously expected to be deployed this decade is not built. This would cause annual home electric bills to jump $70 by 2031. This corroborates other analysts who found, in some cases even higher electricity price increases. The Clean Energy Buyers Association forecasts an increase of $110 in household electricity spending by 2026.

Force Americans to pay the oil and gas industry an additional $339 billion for gasoline and $75 billion for electricity by 2035.
