The World surpasses 40% clean electricity with Europe leading as a 'solar superpower'.

The world generated more than 40% of its electricity from low-carbon sources in 2024, for the EU it's 71%.

Solar energy is soaring in a targeted race to build an entirely clean electricity system. Solar in the EU almost doubled in the three years to 2024 to account for 11% of electricity.

Can renewable energy survive climate change?

As #droughts reduce #hydropower and #clouds dim #solar output around the world, experts say #meteorology and #ClimateScience must be at the heart of the #energy transition.

Yet, even as the push for renewables gains momentum – driven by cheaper technology and an urgent need to slash carbon emissions – experts are waving cautionary flags: Because renewable energy sources depend on weather conditions, climate change is increasingly dictating, and jeopardizing, renewable energy production.

“Highlights:
• A novel method for detecting geothermal components from solar energy dominated LST.
• Using LST time series to eliminate temporal variant solar energy input.
• Uncertainty in anomaly identification quantified by probability measure.
• Capable of revealing LST anomalies caused by geothermal, anthropogenic and surface processes..."

Inverted resistivity model from AMT data showing the subsurface rock resistivity structure in South Mount Meager (figure modified from Hormozzade Ghalati et al., 2022). a) resistivity slice at 500 m elevation (asl) showing two distinct high conductive anomalies and locations of the cross sections. Cross sections b) and c) in W-E direction, and d) and e) in N-S direction. Anomaly C1 is spatially in accordance with the occurrence of hot-warm spring swarms along the margin of the volcanic complex. Anomaly C2 appears in a circular shape, coincident spatially with the core area of the known deep geothermal prospect.

Cayley), EV (Elaho Valley), MG (Mt. Garibaldi), MC (Mountain Creek), WP (Watts Point). The red rectangular marks the study area. b, a Landsat-8 colour image (2017-07-18) showing details of the study area by a summer view of the MMVC with glacier (blue) at high altitude and vegetation cover (green) along the river valley. The red circle indicates locations of geothermal exploration wells, and orange polygons, the known hot springs.

The #ColoradoRiver is shrinking due to #ClimateChange, which means the nation's 2 largest #reservoirs, #LakeMead & #LakePowell, created by #dams, have reached record low levels in recent years amid a #megadrought spanning >2 decades. If #water levels fall much lower, they could lose the ability to generate #hydropower within the massive dams that hold them back, or even lose the ability to pass water downstream.

Carbon capture more costly than switching to renewables, researchers find

For most countries around the world, sourcing energy entirely from #wind, #solar, #geothermal, and #hydropower by 2050 would reduce their energy needs and costs, improve air quality, and help slow #ClimateChange, according to a study in Environmental Science & Technology.

These benefits could be realized at a fraction of the cost of implementing technologies that remove #CarbonDioxide (#CO2) from the air and capture it from stationary emitters like industrial smokestacks.
