Myth No. 1: A grid that increasingly relies on renewable energy is an unreliable grid
Myth No. 2: Countries like Germany must continue to rely on fossil fuels to stabilize the grid and back up variable wind and solar power.
Myth No. 3: Because solar and wind energy can be generated only when the sun is shining or the wind is blowing, they cannot be the basis of a grid that has to provide electricity 24/7, year-round.

Hydrogen '2x as powerful a greenhouse gas as thought before': UK govt study
Global Warming potential (GWP) of #hydrogen is between 6 & 16, 11 the ave — GWP of CO2 is 1. Previous 2001 study put GWP of hydrogen at 5.8 rechargenews.com/energy-transit…
“Any leakage of H2 will result in an indirect global warming, offsetting greenhouse gas emission reductions made as a result of a switch from fossil fuel to H2,”
"much smaller molecule than #methane.. much more easily leak from existing #naturalgas pipelines if used to carry H2"
report does not take into account GWP of PRODUCING hydrogen, only impact of H2 released into atmosphere
electrolysis production of H2 wld result in 9.2% leakage frm “venting & purging”, but this wld fall to 0.52% “with full recombination from purging & crossover venting”.
Guess they're talking about Canada & @liberal_party re #BayduNord#TMX#LNGCanada #oldgrowrh#clearcut 👇
"Ongoing investments in fossil fuel infrastructure & clearing large swaths of forest for agriculture undermine the massive curbs in emissions needed to meet Paris goal"
Such cuts would be hard to achieve without without drastic, economy-wide measures, the panel acknowledged. It’s more likely that the world will pass 1.5C
#JustinTrudeau never had any INTENTION of meeting 2C much less 1.5C target
Many experts say #CCS is UNFEASIBLE with current technologies, & even if it could be done it would be far costlier than preventing the emissions in the first place."
ILLEGAL for foreigners to buy any residential properties in Canada for the next two years.
foreign buyers ban will apply to condos, apartments, and single residential units. Permanent residents, foreign workers, and students will be excluded from this new measure. Foreigners who are purchasing their primary residence here in Canada will be exempt.
Unprecedented die-offs, melting ice: Climate change is wreaking havoc in the Arctic and beyond #me6 phys.org/news/2021-12-u…
"In last 5yrs scientists have observed animal die-offs of unprecedented size, scope & duration in waters of the Beaufort, Chukchi & northern Bering seas, while recording the displacement & disappearance of entire species of fish & ocean-dwelling invertebrates"
Why nuclear power will never supply the world's energy needs
Analysis has concluded that nuclear power cannot be globally scaled to supply the world’s energy needs for numerous reasons. phys.org/news/2011-05-n…
The results suggest that we’re likely better off investing in other energy solutions that are truly scalable
to supply 15 TW with nuclear only, we would need about 15,000 nuclear reactors. In his analysis, Abbott explores the consequences of building, operating, and decommissioning 15,000 reactors on the Earth,
