Large scale electricity generators, unconcerned with end-use, want to sell you more electricity, argues Walt Patterson of the Hoffmann Centre for Sustainable Resource Economy, based at Chatham House. But the arrival of small-scale, localised and micro-grid suppliers could see the electricity generation business turned on its head. It opens the door to the selling of the service – light, heat, refrigeration, motive power, information – rather than … [Read more...]
Will Toyota’s new battery design solve the looming shortage of vital metals for renewables?
We all know the important part played by lithium in battery manufacture. But there is a longer list of metals - including copper, cobalt and neodymium – that must ramp up supply for the continued rapid growth of EVs, solar, wind and other renewables technologies. EVs alone will increase the consumption of copper nine-fold by 2027. Cobalt prices already doubled in 2017. Neodymium use will rise by 700% in the next few decades to satisfy our need … [Read more...]
IEA: Battery storage races to keep up with solar and wind’s demand-matching challenges
Yesterday’s article from the IEA posed the question: will solar’s inherent intermittency slow its rise as a major power supply. For variable renewables like solar and wind to grow to over 50% of global capacity additions by 2040, storage technology must keep up with this pace. For this to happen, “flexibility” – the ability of the power system to quickly adapt to changes in power supply and demand – needs to grow by some 80% in the next decade … [Read more...]
IEA: solar’s exponential growth could make it less competitive, not more
Solar’s current growth trajectory means a doubling of annual deployment every three years. But despite further expected reductions in some cost areas (e.g. cheaper tech and economies of scale), the IEA’s new VALCOE (value-adjusted levelised costs of electricity) metric calculates that solar’s relative competitiveness per unit added will actually decline as its inherent demand-matching issues scale up with the growth. Brent Wanner, WEO Energy … [Read more...]
EXCLUSIVE: Chinese government’s plan to meet the Paris goals
China is leading the energy transition as the world’s largest producer, exporter and installer of solar panels, wind turbines, batteries and electric vehicles. It has a clear lead too in renewable energy patents, ahead of the U.S. and twice that of the EU. But it is also still heavily dependent on coal, the air pollution in its cities is legendary, and the economy is expected to quadruple by 2050. Against this background, Kaare Sandholt, Chief … [Read more...]
Battery manufacture must take a global leap forward to ensure a sustainable and just transition
The global battery market is surging. By 2040 the global energy storage market is projected to attract $620 billion of investment. Over the past decade, the rechargeable lithium-ion battery market doubled on average every three years. To cope with this growth, we need the development of a sustainable and low-carbon value chain for batteries in order to contribute to the implementation of the 2015 Paris Climate Agreement, says Martin Brudermüller, … [Read more...]
Solar energy is green. Solar panels are not. AI can revolutionise their design
Solar panels are manufactured at 2,000˚C, a temperature so high it requires fossil-fuel power. They are also made using rare earth elements, the supply of which has both capacity and political issues. A new and global project is using artificial intelligence (AI) to rapidly create new designs with new materials that can make their manufacture greener and cheaper. The new designs may even bring their manufacture back to your home country, says … [Read more...]
Desert solar – the race for the world’s biggest farm
When solar power was first conceived decades ago, the obvious locations for the farms were the world’s great deserts. Sure enough, the biggest farms are being built there reports Arasan Aruliah. … [Read more...]
UK nuclear plans are in tatters. But current incentives help gas, not wind and solar, step into the gap
The scrapping of plans for a new nuclear power station in Cumbria and the suspension of work on another in Anglesey have put the brakes on the UK’s nuclear future. But the government appears more keen to fill the gap with gas rather than renewables. David Toke of Aderdeen University criticises the current incentives and regulations and makes the case for wind and solar. … [Read more...]
How much subsidy does solar need, and for how long?
Schalk Cloete presents his latest paper looking at what affects the profitability of an investment in a power sector. After reviewing onshore wind and nuclear, he now looks at solar. His analysis of coal and gas are to come. Intermittency, market share, maintenance, integration costs and other factors are modelled in detail to help predict solar’s future. *This article is brought to you via our new author platform. If you have an article you … [Read more...]
Electric metering should break its link with power consumed and create it directly with the costs of delivery
In a world where electricity is generated from non-renewables (oil, gas, nuclear) our meters measure and charge us for electricity delivered, as if it was a fuel being consumed. Going forward, the cost should be measured against what is actually being consumed. In a renewables world – particularly 'run-of-the-river' hydro, wind and solar - that’s not the electricity. It’s the wear and tear on the infrastructure. Treating these types of renewable … [Read more...]
Nuclear power at the mercy of government subsidies while costs remain high
What affects the profitability of an investment in nuclear energy? What are the risks? Energy researcher and analyst Schalk Cloete presents his latest paper on the matter. He looks at the various effects on nuclear power investment, including the rise of other competing renewable energy sources, and the changing price of energy. *This article is brought to you via our new author platform. If you have an article you want to submit to us for … [Read more...]
Report maps out the new geopolitical power dynamics created by renewables
A new report by the Global Commission on the Geopolitics of Energy Transformation says the new energy age will profoundly reshape relations between states and regions. It will bring “A New World” of power, security, energy independence and prosperity. It will also reshape the geopolitical map, just as fossil-fuels have done over the last 200 years. No nation will be unaffected. … [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...]
Norway’s renewables exports to increase 8-fold by 2030
Already, Norway’s renewable energy sector generates $1.2bn in export revenues today. Now an analysis of commitments by both private and state actors shows that that figure should rise 8-fold by 2030. Terje Osmundsen, CEO of Empower New Energy, adds up the numbers, identifies the key businesses and state operators, and shows how renewables exports can help both Norway and developing countries in danger of being left behind. … [Read more...]
