In 2018, 80% of India’s total energy lending went to renewables. Coal got the rest, a major fall compared to 2017. No wonder, given coal plants have been running at below 60% utilisation for two years with the operators suffering huge losses. Renewables are now undercutting coal and getting cheaper. And shortages in water – needed for plant cooling – just add to their woes. Vibhuti Garg at IEEFA catalogues the problems, then describes the … [Read more...]
Non-Wires Alternatives for grid expansion: what the U.S. can teach Europe
Grid expansion usually means more power stations and wires. Far from simple, and very expensive. Non-Wires Alternatives (NWA) solve the problem differently by reducing net demand. Modern methods of energy efficiency, demand response, storage, and distributed generation are coordinated and used instead, under the banner of Distributed Energy Resources (DER). Crucially, it can cast utility firms in the role of market makers, not just generators and … [Read more...]
Energy security v Transition in Algeria, Egypt, Morocco, Turkey
Like most developing countries, the challenge of growing economies, increasing population and rapid urbanisation puts energy security above emissions reductions. So it is for Algeria, Egypt, Morocco and Turkey, says Duygu Sever in her report for IFRI Centre for Energy & Climate. In this article she explains that all four countries nevertheless have high renewables deployment potential, and have already embraced wind and solar. To accelerate … [Read more...]
New solar cell allows a photon to release two electrons, not just one
In conventional silicon-based solar cells, each photon of light can only knock loose a single electron, creating electricity. That’s even if the photon carries more than enough energy to do so. One hammer, one nail. Now, for the first time researchers at MIT and Princeton University in the U.S. have got high-energy photons to strike silicon and kick out two electrons instead of one, opening the door for a new kind of solar cell with greater … [Read more...]
District Heating: heat-as-a-service and sector coupling
Space heating and hot water account for around 70% of energy consumption in residential buildings. Any progress in buildings efficiencies will see overall energy consumption decline. But that presents a serious challenge to the existing business model: why invest in a sector that’s selling less energy? The answer is to change that business model, says Oskar Kvarnström, Energy Policy Analyst at the IEA. In doing so new doors are opened. At the … [Read more...]
Energy Efficiency should target inefficient use, not all use
Energy efficiency should not just be a matter of reducing energy consumption. As renewables grow pricing and profits should encourage renewable consumption. After all, renewables aren’t a problem. And greater renewables consumption means less fossil fuels. Yet consumer pricing models with a low fixed price + high variable rate are designed to discourage all consumption, warns James Bushnell of the Energy Institute at Haas. He says we must … [Read more...]
China’s industry: Deep decarbonisation progress and challenges
Across the world, industry is regarded as a hard-to-decarbonise sector, and an emissions priority. In China it’s responsible for over 65% of its energy consumption and 70% of carbon emissions. Ji Chen and Shuyi Li of the Rocky Mountain Institute (RMI) look at the highlights of China’s efforts, and reference them against the RMI’s Reinventing Fire: China analysis. Efficiency, electrification, CCUS, hydrogen and “recycle and reuse” all play an … [Read more...]
India aims for competitively priced superefficient ACs
Cooling represents over 6% of the world’s total final energy consumption, and growing. Of the 2.8bn people living in hot tropical regions only 8% have air conditioners (ACs) - it’s 90% in the US and Japan. With growing affluence, most will buy cheap entry-level ACs, with their low efficiency and polluting refrigerants. To cope, India will need 600GW of new power generation capacity by 2050 – equivalent to the installation of 1,200 coal power … [Read more...]
IEA: Global energy investment stabilises at $1.8tn after 3 years of decline
Three consecutive years of declining global energy investment has ended. But it’s not risen, just stabilised at $1.8tn, according to the IEA’s latest report World Energy Investment 2019. To meet the Paris targets investment in efficiency needs to rise substantially, and double by 2030 for renewables: they have stalled for both. To meet soaring global energy demand oil and gas investments need to rise too. That demand is seeing cheap coal still … [Read more...]
Britain has shifted 30% of its electricity away from fossil fuels in just nine years
Britain’s extraordinary energy transition is in part down to increased energy efficiency: put simply, less electricity was needed, whatever the source. But coal is still essential during spikes in demand. Given coal generation is due to be phased out by 2025, the country will need to find alternative power sources to cope during extreme weather events. And that overall decline in electricity demand is sure to be reversed as more vehicles and … [Read more...]
