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...]
“Consuming less energy may act as disincentive for investment in renewables”
According to Anthony Patt, Professor of Climate Policy at the ETH Zürich in Switzerland, the less we spend on energy, the less attractive renewables can look to businesses and investment markets. Such remarkable insights fly in the face of received wisdom and defy logic. Patt claims his models show that doubling current energy efficiency improvement rates buys us only one extra year to hit the Paris targets. Really? - This is how Anthony … [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...]
EU electricity supply from RES off course for 2030 – so is it more nuclear or gas?
Last year’s strong reported performances for the share of clean energy in the UK and German energy mixes paint a rosy picture. It is the result of billions in investment and strong signals from Brussels and the COP series. Looking more broadly across the EU though, the share actually decreased by 17% from 2016 to 2017. Furthermore, due to lack of investment stretching back as far as 2011, the rate of growth has dropped significantly putting RES … [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...]
Low oil price alongside rise in renewables sees Oil & Gas slide to bottom of S&P 500
In December we reported that in 2018, the U.S. became the world's leading oil producer for the first time since the 1970s. It is tipped to produce 12 million barrels of oil per day this year (up approximately 10% year on year), and over two-thirds of it will come from shale producers. But the consequent squeeze on the oil price meant U.S. Oil & Gas firms ended the second year in a row at the bottom of the stock market. IEEFA’s director of … [Read more...]
Investment risk: nuclear high, new load-following fossil fuel plants low
In the current policy environment many energy technologies can appear attractive with the right set of assumptions: discounted clean energy technologies (wind, solar and nuclear) where the discount rate is heavily influenced by risk (see graph) and, perhaps surprisingly, new load-following fossil fuel plants (especially natural gas) where continued wind/solar technology forcing actually provides substantial upside potential. CCS researcher Schalk … [Read more...]
Can Teresa Ribera transform Spain into a green champion?
In a draft bill released on 13 November, the Spanish government is proposing to ban fossil fuel subsidies and fracking, reduce greenhouse gas emissions by 20% by 2030 (37% compared to current levels) and 90% by 2050, boost the share of renewables to 35% (70% of power generation) in 2030 and discourage diesel and petrol cars. Natalie Sauer of Climate Home News portrays the woman behind the plan, ecological transition minister Teresa Ribera, and … [Read more...]
Study says no way to decarbonise the gas sector by 2050
Gas industry advocates argue that expansion of gas infrastructure is justified because it will be possible to switch to low-carbon gases such as hydrogen and biomethane in future. But research by the International Council on Clean Transportation (ICCT) predicts that biomethane production will remain modest, even with massive subsidies. … [Read more...]
Bioenergy carbon capture: Climate snake oil or 1.5C panacea?
Most models for meeting 1.5℃ or 2℃ climate change targets suggest we will be using bioenergy carbon capture and sequestration (BECCS) to mop up the world’s total annual CO2 emissions by around 2070 (for 2℃). This means moving from today’s three BECCS power plants to 16,000 by 2060. But, explains Paul Behrens of Leiden University, large-scale BECCS is a “monumentally tricky idea,” and, while aiming to fix climate disruption, it makes many things … [Read more...]
Are solar microgrids the future in the developing world?
Setting out to evaluate the real-world performance of solar microgrids in developing countries, a team from the Energy Institute at Haas partnered with startup Gram Power to provide small smart grid systems to unelectrified rural communities in India. While many industry experts see microgrids as important for future electrification, what the team found was that few communities wanted them, and they were difficult to implement and operate. … [Read more...]
Energy transition: The greatest switch capital markets have ever seen
Even the most engaged energy pundits tend to gloss over what may be one of the biggest changes of all in a clean energy transition: how we pay for and finance the energy we use, and what that may mean for the investors, industries and companies that provide that energy. David Nelson of Climate Policy Initiative explains why investment strategies, financial markets and business models also need to transform. … [Read more...]
Tesla big battery defies sceptics, sends industry bananas over performance
It’s less than a year since the Tesla big battery was installed at Hornsdale in Australia and the world’s largest lithium-ion battery has exceeded all expectations, says Giles Parkinson of Reneweconomy.com. Quicker, cheaper and with greater reliability, versatility, accuracy and efficiency than predicted, the storage system also looks set to provide a fast return on investment – results that have led to a rash of new battery projects in the … [Read more...]
