BP’s latest projections, released last week, once again concede that their previous reports have been overestimating fossil fuel consumption and underestimating renewables. Yet BP still predicts total energy demand will grow indefinitely thanks to overall global growth, and fossil fuels will always be needed. But Simon Evans at Carbon Brief shows how these projections contrast starkly with McKinsey’s, who find that the efficiency of renewables … [Read more...]
Can nuclear compete for a bigger role in the transition?
With plans to phase out coal-fired generators in most of Europe, nuclear is trying to compete with gas to become the most viable baseload power source to accompany renewables on the path to net-zero emissions. Both technologies have their advantages. Gas is competitively priced while nuclear generates power with almost no emissions. Right now, gas's cost advantage is evidently great enough to tip the balance. If nuclear advocates are to … [Read more...]
Stop selling electricity, start selling the service: light, heat, mobility, information
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...]
Corporate PPAs: renewables-rush as governments step back
Costs of developing clean energy capacity are falling and the industry is moving from being supported mainly by state subsidies to a more commercial footing where projects are supported by corporate backing, with EU, national or regional targets providing a foundation for the market. The US sportswear giant Nike has signed its first power purchase agreement (PPA) for renewable power in Europe, committing to buy 40MW of wind power from a 111MW … [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...]
South East and Eastern Europe part II: EU can help bring far-ranging benefits of a meaningful energy transition
In Part 1 of this special report, Komila Nabiyeva demonstrated how investment conditions in South East and Eastern Europe, South Caucasus and Central Asia make it almost impossible to justify development of renewables infrastructure on any great scale. That being the case, she calls on the EU to play a greater role. Their initiatives are already making a difference. This is encouraging because it shows that with more EU engagement, a more … [Read more...]
EXCLUSIVE: Geothermal could represent a far bigger share of renewables
The IEA says geothermal energy could account for only 3.5% of annual global electricity production and 3.9% of energy for heat (excluding ground source heat pumps) by 2050. But is this down to short term thinking? Geothermal could make a much bigger contribution to renewables, provided it is put onto the fast track like wind and solar, says Alexander Richter, President of the International Geothermal Association. … [Read more...]
Electric buses: China leads through policy ambition but Europe could overtake
News comes of another renewables record for China. Shenzhen based manufacturer BYD has launched the world’s largest pure electric double decker bus fleet, to be delivered to the city of Xi’an. To illustrate China’s drive to dominate this market, they have already won the international tender to deliver 37 of a total of 68 new electric double decker buses to London, where the red double decker is an icon. That’s more than the remaining 31 that … [Read more...]
Special report: South East and Eastern Europe PART I – Subsidised fossil-fuel power blocking the way for renewables
Right on the border with Western Europe, countries in South East and Eastern Europe, South Caucasus and Central Asia have enormous potential for renewable energy, but it remains largely untapped. A stark contrast to the situation a few kilometres further North and West. The region’s fossil-fuel and nuclear subsidies are among the highest in the world. The subsidies and accompanying low electricity prices translate to an unrealistic cost of … [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...]
Digitalisation is changing the energy landscape
The energy sector is already using data in sophisticated ways to meet a wide range of challenges, from fault prediction in grid networks to the delivery of personalised energy to households. As more data becomes “big data” and smart devices proliferate along the value chain, Matt Brown and Ravi Mahendra of Pöyry Management Consulting make their predictions for more digitalisation in the coming year. … [Read more...]
Germany: wind installation growth beset by legal challenges
According to the German wind industry, new installations have ground to a halt due to a combination of red-tape holding up licences and because “almost every authorisation is sued”. A joint statement by the German Wind Energy Association (BWE) and VDMA Power Systems (the trade association for power systems) has called on the government to streamline licensing procedures and eliminate administrative barriers to new turbines, otherwise the … [Read more...]
Heat pumps vs boilers: renewables vs efficiency?
Heating and Cooling (H&C) is responsible for 50% of energy use in the EU and is still heavily dependent on fossil fuels. The opportunity to change your installed system won’t come up more than a couple of times before 2050 so the choice we make now has a large, lasting effect on the breakdown of the entire energy mix. H&C is the term used for the vast amounts of energy used to regulate the temperatures of the buildings we live and work … [Read more...]
