By Sean Ratka Limiting the global average temperature rise to 1.5-degrees-C will require all sectors of the economy to reach zero carbon dioxide (CO2) emissions early in the second half of this century. A growing number of countries are committing to such net-zero-emission goals. There is general agreement that renewable energy and energy efficiency are…
By [email protected] Blockchain’s energy sector applications range from the highly speculative — think peer-to-peer energy-trading using cryptocurrency raised in initial coin offerings — to more incremental efforts, grounded in the real-world challenges of operating an increasingly decentralized power grid. The latter describes how utilities and energy market operators are applying blockchain as a distributed ledger…
By Joshua S Hill Wood Mackenzie research predicts solar PV costs will continue to fall through the 2020s, driven by three key improvements to module efficiency.

By [email protected] U.S. homes and commercial buildings consume roughly two-fifths of the country’s overall energy and three-fourths of all electricity, and account for most of the peak electricity demand that drives generation and power grid infrastructure costs. Each of these statistics points to different solutions for reducing buildings’ carbon footprint. Shifting heating from fossil fuels…
By [email protected] Utility pilot projects aren’t famous for being standout financial successes. Usually, the goal is to verify a technology in the field before attempting broader deployment. Sometimes nothing follows the pilot. Vermont utility Green Mountain Power not only verified the efficacy of residential batteries for meeting grid needs, but it also saved its customers…
By [email protected] SunDensity, a solar startup promising 20 percent power output gains* due to specially coated glass, raised $2.5 million in initial financing to begin commercializing its product. If commercially successful, the technology could measurably increase the output of solar panels, reducing the number of modules needed to produce the same amount of electricity and…
By WPED Staff Tetrahedron today launched a novel crane for the installation of the next generation of offshore wind turbines, designed to fit on both existing and new jackup wind turbine installation vessels. The increasing size of wind turbine generators sets a challenge for the offshore wind installation industry. Existing jackup vessels are rapidly becoming…
By Blagojce Krivevski Electric range of up to 59 kilometers (36.7 mi) in the NEDC (47 kilometers (29.2 mi) in the WLTP cycle), a sporty character, and great everyday usability: Audi is presenting the Q8 with plug-in hybrid drive. The new model closes the last gap in the Q8 range and provides an innovative combination…
By Rafael Herzberg These days a long list of energy related options is potentially available for industrial, commercial and institutional energy users. They range from purchasing energy as commodities (power, gas, biomass, etc.), developing energy efficiency projects (inside the fence) and power projects such as generation, cogeneration and high voltage access (to the fence and/or…
By [email protected] Duke Energy has upped its net-zero carbon by 2050 goals, pledging to eliminate methane emissions from its natural gas business by 2030 through a combination of better pipeline leak detection, more efficient operations, and investing in renewable natural gas to reduce the carbon intensity of its supplies. The new goals outlined in Duke’s…
The buses are as efficient as electric equivalents, with refuelling taking less than 10 minutes and offering a greater range. Water is the only emission from the vehicles which reduces carbon emissions and the new buses continues to contribute to the city’s commitment to tackling air pollution.

Researchers working to maximize solar panel efficiency said layering advanced materials atop traditional silicon is a promising path to eke more energy out of sunlight. A new study shows that by using a precisely controlled fabrication process, researchers can produce multilayered solar panels with the potential to be 1.5 times more efficient than traditional silicon…
By [email protected] (Bengt Halvorson) Yes, Jeep could have electrified its Wrangler in a simpler and more efficient way. But for the iconic off-roader, that would have been beside the point. Perhaps even more than for the Renegade 4xe and Compass 4xe plug-in hybrids launched for the European market in June, the Wrangler needed to be…
A study of a solar-energy material with a bright future revealed a way to slow phonons, the waves that transport heat. The discovery could improve novel hot-carrier solar cells, which convert sunlight to electricity more efficiently than conventional solar cells by harnessing photogenerated charge carriers before they lose energy to heat.
