In Texas, income from electricity sales does not even cover the direct costs of coal power plants. But their hidden costs are much higher, explains Daniel Cohen of Rice University in Houston. Courtesy The Conversation. … [Read more...]
Taxing carbon may sound like a good idea but does it work?
Exxon Mobil is financing lobbying for a US plan to tax oil, gas and coal companies for the carbon they emit. But do carbon taxes work to reduce greenhouse gas emissions? The evidence is underwhelming and support for the proposal is not down to altruism, says Paul Griffin of the University of California, Davis. In his view, what would impact climate change is for energy companies to disclose their carbon risks and footprints. … [Read more...]
Coalâs cost increase leaves no cause for celebration
Coalâs carbon impact is clear from the fact that it produces 20% of electricity and 65% of EU power sector emissions. But even with EU coal prices at a five-year high, we are unlikely to see short-term European coal emissions reductions. Emissions Trading System prices would have to double to push coal out of the EU electricity mix, says Paul Deane of University College Cork's Environmental Research Institute. … [Read more...]
The impact of electric vehicles on electricity demand
Many in the industry are relying on electric vehicles (EVs) to reverse the downward trend in global electricity consumption. But a new report from Redburn, a UK research and investment company, suggests the growing energy efficiency of EVs means that the industry and investors may have to look elsewhere for significant boosts in demand for electrical power, says energy expert Fereidoon Sioshansi of EEinformer. … [Read more...]
Aligning the IEA Sustainable Development Scenario to Paris goals
As part of its World Energy Outlook 2018 report, on 13 November the International Energy Agency will publish its latest Sustainable Development Scenario that it claims shows governments and companies how to reach Parisâ climate change goals. To date, itâs fallen short â perhaps because it thinks the goals are too difficult to achieve, says Greg Muttitt of Oil Change International, which is calling on the agency to start showing how those goals … [Read more...]
US shale has a glaring problem
With oil prices high and production booming, 2018 was supposed to be a year of profits for US shale oil and gas companies. A report from the Institute for Energy Economics and Financial Analysis (IEEFA) and the Sightline Institute shows that hasnât happened. As 3Q 2018 results start coming in, investors around the world should be considering if there is a fundamental problem with the fracking business model, says Nick Cunningham of Oilprice.com. … [Read more...]
Europe prepares a net zero emissions plan for 2050: use the EUenergy App to understand it
The European Commission is drafting a new 2050 climate and energy strategy that will set out a vision for net-zero emissions in Europe by 2050, to be unveiled before the next round of UN climate talks, in Katowice, Poland this December. Energy Post reports on the latest internal reflections on the new strategy, using the EUenergy App, jointly developed by Energy Post and Shell, to put the ideas in context. … [Read more...]
Time to re-think Britainâs capacity market
Answering the call for opinions for the UK capacity market review, Gerard Wynn of the Institute for Energy Economics and Financial Analysis (IEEFA) says its time for a rethink. Since its introduction to ensure energy security, 75% of payments have gone to existing coal, gas and nuclear plants, and only 10% to modern assets. By continuing with market reforms and building interconnections with Europe, the UK can have an efficient, market-led … [Read more...]
Bioenergy carbon capture: Climate snake oil or 1.5C panacea?
Most models for meeting 1.5â or 2â climate change targets suggest we will be using bioenergy carbon capture and sequestration (BECCS) to mop up the worldâs total annual CO2 emissions by around 2070 (for 2â). This means moving from todayâs three BECCS power plants to 16,000 by 2060. But, explains Paul Behrens of Leiden University, large-scale BECCS is a âmonumentally tricky idea,â and, while aiming to fix climate disruption, it makes many things … [Read more...]
A blacklist of the worldâs top 120 coal plant developers
Nearly 1,400 new coal power plant developments are planned or under construction in 59 countries that would add 33% to coal power capacity. But the risks of investing in such projects are growing, and many banks and investors are looking to move away from coal. To help them, non-governmental organisation Urgewald has created a database of the worldâs top 120 coal plant developers, says Kathy Hipple of the Institute for Energy Economics and … [Read more...]
RWEâs lignite: between a rock and a hard place
The power giant RWE has faced fierce opposition to its plans for expanded lignite mining in Hambach forest, Germany. But as energy expert Gerard Wynn writes, a new report from the Institute for Energy Economics and Financial Analysis suggests there could be four more significant reasons for RWE to renounce its commitment to coal. Courtesy of Energy and Carbon. … [Read more...]
Why we canât reverse climate change with negative emissions technologies
The United Nationâs panel on climate change said that technologies to remove CO2 will be necessary to limit global temperature rise to only 1.5oC. But these techniques are largely unproven, and the technical, economic and environmental barriers of negative emissions technologies (NETs) are very real, states Howard J. Herzog, Senior Research Engineer at Massachusetts Institute of Technology and a leading expert in CO2 capture and storage. … [Read more...]
How can gas contribute to the achievement of EU climate targets
What role is there for gas in the European energy system over the next decades? Some believe the EU must give priority to coal-to-gas switching. Others see no role for natural gas at all in the long run and argue that EU policy must promote only ârenewableâ gas. An Energy Post panel debate in Brussels, sponsored by Nord Stream 2, saw conflicting views sound off against each other. Meanwhile, a new âGas for Climateâ initiative proposes a 10% … [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...]
