In Maryland getting several solar quotes. 100% intent on owning, but one company, SEW (owned by Comcast), has a new type of leasing that had me crunching numbers (integrates 30% 3rd party rebate, can prepay the lease to have zero payments, zero escalation, SEW takes care of system for length of lease, table of buyout values over life of lease if want to switch to owning).

Does anyone else have experience with this program? (understanding it is fairly new)

Strategic oil inventories have reached a 40-year low, and experts warn their continued depletion could damage the underground caverns where the reserves are stored.

Last week, the Strategic Petroleum Reserve (SPR) plunged below 300 million barrels for the first time since the 1980s, when the reserves were being filled, according to the Department of Energy. That pool is expected to drain further to 243 million barrels as the U.S. releases 172 million barrels to manage severe supply disruptions and rising energy costs due to the Iran war.

Those reserves are kept in 60 salt caverns across two sites in Texas and two sites in Louisiana, each thousands of feet underground. They have a total storage capacity of 714 million barrels. But as oil is drained from these reserves, the integrity of the caverns may be imperiled.

“I don’t know anyone who believes we can go below 300,” Amos Hochstein, a senior energy advisor for former President Joe Biden, told CNBC on Saturday. “I know plenty of people who think we can’t get near 300 because physically you will damage the caverns where the oil is stored.”

The Department of Energy denied Hochstein’s claim that the changing inventory levels risk harming the caverns.

“The caverns are always full. All that changes is the ratio of oil and water that is filling them,” DOE chief spokesperson Ben Dietderich told Fortune in a statement.

The Iron Man suit is powered by the arc reactor and its basically an ultra super condensed battery that can power anything and its renewable energy on top of that. I know that the arc reactor is fictional and that the vast majority of it is made up stuff. My question is if there is any real life science that is applied to the arc reactor? In Iron Man 2 there is a plot point where the palladium behind the arc reactor is poisoning Tony so he created a new element to fuel the energy and that is used for the rest of his appearances. So creating a new element stuff can be ignored, but in IM1 we know that one of the core components behind the arc reactor is palladium. So from what we know about the arc reactor technology, is there any real life science that is being applied to the fictional energy source?

Every winter I think about how much energy I'm blowing to keep my food frozen and refrigarated. It's so cold outside, I'm having to keep the taps dripping. The heater is blasting. And at the same time, I'm burning energy to keep my food cold. Wouldn't it make more sense to build fridges/freezers in an exterior facing wall, where they can work with the outside air during the wintertime, and the inside air in the summertime?

Australia has had huge success with its « Cheaper Home Batteries Program » with homeowners snapping up batteries, leading to dramatic reductions in wholesale energy prices as peak grid demand has fallen.

Now Australia’s most populous state, New South Wales, is proposing to extend generous incentives to businesses and apartments that cut up front costs by up to 40% for battery storage systems between 20 kWh and 30 MWh, with the most generous benefits for businesses that also install solar.

Great to see Australia continue to lead the way on distributed solar and batteries.
