"Closing a gap in our climate plans - Report says the state's heat pump incentives are inadequate"
"THE RECENT report from the Commission on Clean Heat is short on numbers and, like any “consensus report,” it leaves some important issues unresolved. But it does identify the challenges we face in decarbonizing buildings in Massachusetts and offer an inventory of options.

The state’s basic strategy for cutting carbon emissions is to electrify almost everything while making almost all of our electric power sources carbon-free. Electrifying buildings means converting their heating sources to electric heat pumps; conversion to heat pumps usually requires weatherization. As the commission notes, the scale of the transition is huge. According to the state’s climate plan (page 8), in 2050:
  • All or nearly all new buildings will have been built according to very high standards of energy efficiency and weatherization . . . and will utilize clean heating technologies.
  • The vast majority of the Commonwealth’s more than 2 million individual buildings that were already in existence in 2022, including [low and moderate income] housing units, will have undergone significant energy efficiency and weatherization retrofits and will use high-efficiency electric appliances for heating, cooling, cooking, and hot water."

"How do floating wind farms work? - They will be put to the test with new California leases"
"NORTHERN CALIFORNIA has some of the strongest offshore winds in the US, with immense potential to produce clean energy. But it also has a problem. Its continental shelf drops off quickly, making building traditional wind turbines directly on the seafloor costly if not impossible.

Once water gets more than about 200 feet deep – roughly the height of an 18-story building – these “monopile” structures are pretty much out of the question.

A solution has emerged that’s being tested in several locations around the world: wind turbines that float."
