Managing energy demand spikes

Managing energy demand spikes with seasonal forecasts of heatwaves and cold spells https://horizon-magazine.eu/article/managing-energy-demand-spikes-seasonal-forecasts-heatwaves-and-cold-spells_en.html The impact of heavy droughts, heatwaves and cold spells on energy demand and supplies would be lessened with seasonal climate forecasts that allow energy companies to better predict spikes in usage ahead of time, researchers say. Researchers already have the ability to

A Double First in China for Advanced Nuclear Reactors – IEEE Spectrum

https://spectrum.ieee.org/energywise/energy/nuclear/a-double-first-in-china-for-advanced-nuclear-reactors The most advanced commercial reactor designs from Europe and the United States just delivered their first megawatt-hours in China. Both projects were years behind schedule. On Thursday, 29 June, a 1,400-MW EPR designed in France and Germany synced up to the grid at the Taishan nuclear power plant. The next day the U.S.-designed 1,117-MW

Biltema RCD teardown

Biltema sold this ground fault interrupter (RCD / GFCI) device few years ago (does not seem to sell anymore). It is designed to be connected to 230V AC 50 Hz electrical outlet. The information on the back of the device tells that this will trip at 30 mA leakage current. The symbol tells that this

New Solar Cell “Most Efficient Ever”

http://www.worldwatch.org/node/4803 For the first time, scientists have produced a photovoltaic (PV) cell with a conversion efficiency of 40.7 percent, the U.S. Department of Energy (DOE) reported. The breakthrough cell was developed using a structure called a “multi-junction solar cell.” The technology may allow for lower PV system installation costs ($3 per watt) and lower electricity

Remote Powering over communications cabling (part 3)

Remote feeding is a technology which enables operators to power several remote sites from a central location.  Remote powering implies that the power equipment is not local but some distance away. Remote means that the powering and powered equipment are in separate buildings or at different external locations inside same building.It can be used as

Five key considerations for east-west solar design | PV Tech

https://www.pv-tech.org/editors-blog/five-key-considerations-for-east-west-solar-design Around the world solar developers are turning array designs on their head and choosing to go east-west instead of south- or north-facing like their traditional cousins. While east-west solar arrays may have a reduced total output, the value of the electricity they produce is inherently higher in most markets – They are generating more
