To reduce Nunavut’s dependency on diesel fuel, researchers are trying to use the territory’s gusty weather to develop a wind turbine specifically to generate power for Arctic buildings. “I think it is a really viable [energy] option,” said Jill Hass, an engineer and clean energy manager with Polar Knowledge Canada, the...
"Public investment is more flexible & can adopt a system-wide approach, as opposed to one blinkered at the level of the project." The urgent need to build transmission INFRA at dramatic pace, scale, & geographic scope is clear. To decarbonize the power sector, we’ll have to physically rebuild the grid once-over in the coming decades to connect & facilitate a hopeful explosion in new renewable gen. cap. across our contin-."
World’s biggest solar farm goes online, big enough to power a country
"A recent report by the International Energy Agency (IEA) described #China’s drive towards #renewables as “extraordinary”, with the country commissioning as much solar capacity last year as the entire world did in 2022.
“China accounts for almost 60 per cent of new renewable capacity expected to become operational globally by 2028,” the report stated."
#ClimateChange#Renewables#FossilFuels#RenewableEnergy: "Countries' climate plans are not yet in line with a goal to triple renewable energy capacity worldwide by 2030 which was set at the COP28 climate summit in Dubai last year, a report by the International Energy Agency (IEA) said on Tuesday.
The target would involve increasing installed renewable energy capacity to at least 11,000 gigawatts (GW) by the end of the decade, compared to 4,209 GW in 2023.
Very few countries - just 14 out of a total of 194 - have included specific targets for total renewable power capacity for 2030 in their commitments under the Paris Agreement climate pact, called nationally determined contributions (NDCS).
Official commitments in current NDCs amount to 1,300 GW – just 12% of what is required to meet the global tripling objective set in Dubai, the IEA said."
Like most innovative IDUs, #geothermal as an energy source, will get cheaper.
In Mar, J Shah, DIR: Energy Dept’s Loan Project Office: $25B in investment over the next 5 yrs <cost of the last nuclear plant to be built -could begin a rolling snowball of funding that could power b/w 80-260M HHs by midcentury with clean, reliable power.
Next gen. of geothermal: currently in its infancy -first few projects will be expensive & high-risk as the IDU gets-.
IEA executive director Fatih Birol: "This report makes clear that the tripling [#renewables] target is ambitious but achievable – though only if governments quickly turn promises into plans of action” https://buff.ly/3X8yBjz
"As the market and its regulators navigate the turbulence of an #energy system transitioning from fossil fuels to #renewables, experts warn surges [in the spot price] are likely to become more common. The ageing #coal-fired power station fleet is becoming less reliable, and with the development of large-scale renewables and storage lagging, the potential gap between demand and supply is getting larger."
Yesterday on the grid: Early a.m. we charged our EV off the grid (blue). Midday, solar power mostly went to the grid (yellow). Evening, Powerwall battery pumped juice to the grid as part of a virtual power plant (green). Battery fully recharged by 1 p.m. today from solar. #Renewables#VPP#EnergyTransition#Solar#power
#RenewableUK nuclear, wind and solar industries call for urgent action to jumpstart grid decarbonisation
The Nuclear Industry Association, RenewableUK and Solar Energy UK, representing Britain’s three leading zero-carbon power generators, are calling for urgent action to build new wind, nuclear and solar capacity and for a binding target of 100% grid decarbonisation by 2035.
The chart in this article illustrates the "bang for buck" for electricity generation options. Unsurprisingly, renewables come out ahead, fossil fuels come in the middle, and nuclear is the worst. Don't take my word for it; this comes from scientists who've been working on it for decades at the CSIRO. Another takeaway: don't take Peter Dutton's word for it, either.
Mass adoption of clean energy requires massive energy storage, and we’re getting closer! 👇🏼
Thanks to a MIT spin-off company, we have thermal ceramic bricks capable of storing heat for DAYS 👀.
These ceramic bricks can store heat — at temperatures up to 1800 degrees Celsius — for DAYS that can then be used to convert the energy back to electricity when needed.
Exciting! This is the next level of #solar biodiversified #agrivoltiacs farms: solar panels spaced among agricultural crops & planted with plant species that increase biodiversity. 👏
The parcel of land will have a 54 MW agrivoltiacs facility that will:
— host #wildflowers species
— provide as a wild animal shelter
— feature amphibian ponds, #bird baths, nesting boxes, & breeding places to protect endangered Lesser kestrel #birds
The job market is changing as more businesses and agencies spring up to address climate change. Legislation like Joe Biden’s 2022 Inflation Reduction Act is adding more investment in the education required for these fields.
These students will have important skills and plenty of jobs to pursue, and positively impact our transition to clean energy. Win-win.
Switching to renewable energy could save trillions - study
New report says falling cost of renewable energy makes switch from fossil fuels cheapest option.
✈️Turbulence is up ~15%, air travel is more dangerous bc of #climatechange. Are pilots being trained to avoid sudden turbulence? Should some flights be delayed or cancelled for air safety?
TSP Sec Buttigieg: "An increase in flight turbulence is one of the effects of CC that are already upon us in terms of our transp. -the deadly turbulence on a recent Singapore Air flight is "very rare," but... can happen & sometimes it can happen unexpectedly."
