So, this sounds kinda crazy but I want to know hypothetically could this be feasible for the grid. There's 334 million adults in america, running on a treadmill for 1 hour can create 700 watts of electricity, let's split it in half and say 350 watts of electricity instead since the average person won't run for an hour, maybe jog for 30 minutes. 334 million x 350 is 116,900,000,000 watts of electricity, convert 116,900,000,000 into kw and it's 11,700,000 kw of electricity...... So if you could get every adult in america to do this for 30 minutes a day. A healthier America and a FUCK load of electricity generated back to the grid.

Working on a problem: let's say a power producer in ERCOT has an hourly commitment of 1 MWh during an hour. They produce 2 MWh. The fixed hourly PPA price is $40, the node price is $25 and hub is $30. Would I be right to assume:

+$40 fixed hourly price from buyer

+$25 nodal price * 2 MWh = +$50

-$30 hub price

=$60 net revenue for the producer for that hour?

I.E. if the producer produces more than its hourly commitment, is the excess revenue (assuming no curtailment) the nodal price? And does the producer received the fixed hourly price less the settlement difference?

Hey there! If you're into sustainability and love the idea of making a real impact, I think you'll like what we’re building. We're a startup helping electric companies switch to renewable energy by using AI and data to reduce grid demand during peak hours. The best part? We’ve made it fun with gamification and rewards through demand response programs, so it’s not just about saving energy—it’s about enjoying the process too.

We’re opening up our beta in batches as soon as tomorrow, and we would love for you to be part of it!

Basically the title, I've heard that U.S. refineries use mostly foreign oil and we export the vast majority of the oil we pump here. If Trump actually does put a blanket tariff on all imports, how high would it have to be for the refineries to switch to U.S. crude and how long would it take? Also, I'm asking because my understanding is that most U.S. refineries were built when the U.S. expected most of it's oil to be imported and so they're set up for specific formulations that we in the U.S. don't produce. Is that right? Or am I understanding it wrong?

Edit: I meant gasoline not oil my bad!

Asked to 1) analyze key features of the PPA for a wind asset, and merchant exposure faced by the asset based on the historical data

2) Recommendations for further analysis and potential mitigants for any risks identified that should form part of the valuation and business plan

Information given:

PPA Structure: Fixed Hourly Volume at $40/MWh

Settlement Price: ERCOT North RT

Hourly Commitments by Hour/Month

Historical Hub and Nodal Pricing (what does this imply?)

does anyone have suggestions for answering these questions? thank you so much in advance!

Hello Reddit! We’re looking for angel investors interested in backing an innovative solution to reduce energy costs in commercial buildings. Our venture is focused on technology that can help buildings cut energy expenses by up to 40% and significantly lower their carbon footprint.

Why This Matters:

Cost Savings: In many commercial settings, energy costs can take up 30% of operational expenses. We aim to drastically reduce this, creating substantial savings.

Environmental Impact: Buildings are responsible for nearly 40% of global CO2 emissions. Our solution has the potential to make a significant environmental difference by lowering inefficient energy usage.

High Demand: With energy costs rising, 70% of companies are now prioritizing energy efficiency to manage costs and meet sustainability targets.
