solar power

A Washington Examiner report argues that the growing strain AI places on data centers — power demand, cooling needs and land use — could eventually push computing infrastructure into orbit, where satellites would get continuous solar energy. The idea is gaining attention as AI companies face rising energy costs and grid constraints on Earth, though significant technical and cost hurdles remain before space-based data centers become realistic.

Google has announced Project Suncatcher, a research initiative to run machine learning infrastructure on solar-powered satellite constellations in orbit. The idea is to use uninterrupted sunlight in space to power AI data centers without Earth's land and energy constraints. Commenters are debating feasibility, launch costs, thermal management and whether orbital compute could scale.

A major battery storage facility is being built in Waltrop, Germany, at a cost of around 500 million euros. The project would use 800 containers of lithium batteries to store up to 1,800 megawatt-hours of electricity and deliver up to 900 megawatts of power, allowing surplus wind and solar energy to be fed into the grid. It is being discussed as an example of Germany's push to expand grid-scale storage for renewable energy.

Global energy analysis shows wind and solar power capacity and generation continuing to expand rapidly, yet fossil fuel use is rising at the same time rather than being displaced. Commentators note that growing overall energy demand means renewables are adding to supply instead of replacing coal, oil and gas, keeping emissions concerns alive despite record clean-energy investment.

The US Energy Information Administration projects that solar power generation in Texas will surpass coal in 2026, marking a milestone in the state's energy transition. Texas, already the leading US state for both wind and utility-scale solar additions, is expected to see coal's share of its electricity mix fall further as new solar capacity comes online and coal plants continue retiring.

A new player has emerged in the growing conflict over siting solar farms on agricultural land, according to Politico. The dispute pits renewable energy developers seeking open space for large-scale solar projects against farmers and rural communities concerned about losing productive farmland. The identity and motives of this unlikely influential figure are drawing attention as the battle over land use and clean energy intensifies across rural areas.

Questions are being raised over whether the rapid expansion of solar power in the United States is finally losing momentum. Analysts and readers are debating the state of the industry, its growth trajectory, and what factors could be holding back new installations after years of strong gains.

CGTN's RAZOR programme explores whether solar technology can play a role in protecting global water supplies. The report examines how solar power could be used to address water scarcity, from powering desalination plants to pumping and purification systems. As droughts and water shortages intensify worldwide, the intersection of renewable energy and water security is drawing renewed attention from researchers and policymakers.

Google is reportedly testing AI chips for what it calls 'fractionalized' space data centers, an approach that would split computing workloads across satellite-based infrastructure rather than relying solely on terrestrial facilities. The idea points to a growing push among tech giants to move data center capacity into orbit, where solar power and cooling are more abundant. Details on the testing and timeline remain limited.

A new market outlook projects growth in space-based solar power through 2035, driven by rising demand for energy security. The report points to expanding investment and development in the sector as countries look to diversify energy sources. Interest in the technology continues to build as governments and industry weigh its potential role in future energy supply.
