If you are in the NE Ohio area, I'll be giving a talk on Thursday, Oct 8th about Electrification, EVs, & EVA of Ohio with the Kent Environmental Council in Kent, OH. We'll also have EVs on display after the talk. Come join us! 🧪🔌💡☀️💧🔋 evaohio.org/event/attend...
EVs all lined up at the start of the American Solar Energy Society (ASES) EV Rally at the Laketran Transit center at Lorain County Community College.Laketran operates a fleet of 11 battery electric buses. They charge up at 15 minute intervals around the route.

EV update: Our 2026 Toyota BZ is now ~3mo, old. My wife has put 1050 miles on it & the efficiency for mostly city driving is impressive: 4.9 miles/kWh. With our electricity at $0.18/kWh we've spent just $39 to charge at home. 🧪🔌💡☀️💨💧🔋
Driving a Toyota BZ 1,050 miles on $0.18/kWh electricity costs just $39. The car it replaced used to get 32 MPG, which would have cost $134 to drive the same distance on $4.00/US gallon gas or 3.4x more expensive.

Love seeing this. Better operating costs for the school district and better for the communities to not have massive mobile diesel engines belching toxic fumes everywhere they go. We really need all package delivery vans to be required to make the switch. Like the few electric FedEx trucks out there

How much could my school district save if they switched from diesel powered school buses to BEV buses? It works out to somewhere between $5,000 to $9,000 per vehicle or $265,000 to $522,000 per year depending on performance, fuel costs, and fleet size assuming 12,000 miles driven per year. 🧪🔌💡☀️💨💧🔋
A BlueBird diesel school bus get 7 to 10 MPG, while a BlueBird BEV school bus gets 0.72 to 0.66 miles/kWh or 24.3 to 22.3 eMPG. For diesel at $6.67/ US gallon and electricity at $0.159 the diesel buses costs 66.7 to 95.3 cent/mile to drive while the BEV school bus would cost 22.1 to 24.1 cents/mile to dive. That translates into costs of $8,002 to $11,432 for diesel or $2,650 to $2,891 for the electric buses assuming 12,000 miles driving.

I've posted about how total cost of ownerships is lower for BEVs than fossil fuel cars. It's true for trucks, vans and school buses too. School districts are saving money by switching from diesel to electric school buses. Let's look at some examples... 🧪🔌💡☀️💨💧🔋 www.the74million.org/article/as-d...

It’s always funny when folks lament the lack of affordable EV pickups when it’s lobbying by GM and Ford that keep them out. This launched around the time the Lightning did for ~$25k and would be <~$35k here were it not for the competition cancer of GM and Ford lobbying/beneficial tariffs.

Agrivoltaics combines crop or livestock w/ PV solar power. The farmers get two crops on the dual use land. "Common sense" might suggest that shade from the PV system will detract from the agricultural product. But this lamb study from Oregon St Univ. (my Alma Mater!) found the opposite. 🧪🔌💡☀️💨💧🔋 a 🧵

The 2025 IRENA report on Renewable Energy Costs is now available. The LCOE for variable renewable energy sources continued to drop, while dispatchable renewable energy sources saw slight increases in LCOE. Source: www.irena.org/-/media/File... 🧪💡🔌☀️💨💧🔋
A time series plot of the change in LCOE for Renewable power shows that in 2025 CSP is at $115/MWh, Bioenergy is at $89/MWh, Geothermal at $86/MWh, Offshore wind at $78/MWh, Hydropower at $62/MWh Solar PV at $44/MWh and Onshore wind at $33/MWh. A statement from the report reads: "Renewables retained their cost advantage over fossil fuels. Despite the plateau, renewables remained the most cost-competitive source of new electricity in most markets in 2025. Their advantage over fossil fuels also continued to widen. Since 2010, the LCOE of solar PV has fallen by 89%, CSP by 72%, onshore wind by 71%, offshore wind by 63% and bioenergy by 3%. In contrast, the LCOEs of hydropower and geothermal increased by 41% and 53%, respectively."
