Bloomberg NEF forecasts falling battery prices enabling surge in wind and solar to 50% of global generation by 2050

Green Car Congress

The arrival of cheap battery storage will mean that it becomes increasingly possible to finesse the delivery of electricity from wind and solar, so that these technologies can help meet demand even when the wind isn’t blowing and the sun isn’t shining. trillion of that going to wind and solar and a further $1.5

A DIY E-bike Conversion on the Cheap

Cars That Think

Online discussions convinced me, however, that this is the expected behavior when commanding a motor to maintain a fixed amperage in its windings (thus applying constant torque) while under little load. With the power setting fixed, the wheel would spin increasingly fast and the amperage drawn from the battery would steadily increase.

Credit Suisse Predicts Renewable Energy That Is “Too Cheap To Meter” By 2025

CleanTechnica EVs

Credit Suisse says the Inflation Reduction Act will have such a tremendous impact on renewable energy that the US may see the levelized cost of electricity from renewable sources fall to less than 1 cent per kWh hour by 2025 after factoring in all tax and production credits. Now, before we get all gaga over […].

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

The falling cost of making hydrogen from wind and solar power offers a promising route to cutting emissions in some of the most fossil-fuel-dependent sectors of the economy, such as steel, heavy-duty vehicles, shipping and cement, according to a new report from BloombergNEF (BNEF).

Why is Hydroelectricity So Green, and Yet Unfashionable?

Cars That Think

There is no end of gushing about China’s cheap solar panels—but when was the last time you saw a paean to hydroelectricity? Instead, that pure status is now reserved above all for wind and solar. You would think this is about as “green” as it can get, but in 2022 that would be a mistake.
