The IEA’s Sustainable Development Scenario sees the world's geothermal power generation tripling to almost 300 TWh by 2030. That’s because there’s an almost unlimited supply that can provide power, heating and cooling. It’s also a continuous supply uninterrupted by the weather, unlike solar and wind. The plants are small and quiet. For heating, ground-source heat pumps use significantly less electricity than other technologies. Writing for CLEW, … [Read more...]
Latest data shows lifetime emissions of EVs lower than petrol, diesel
Critics of the rapid roll out of electric vehicles correctly say that their factory door emissions (i.e. CO2 emitted during manufacture) are higher than those for standard petrol and diesel cars. Then you have to add the emissions of the local grid (how renewable is it?!) that’s charging your EV. But the numbers behind those calculations are always changing. Eoin Bannon at Transport and Environment describes the findings of their new tool that … [Read more...]
Why a Carbon Border Tax? Because existing tariffs favour dirty over clean imports
Carbon border adjustments are carbon taxes imposed on carbon intensive imports that have not been carbon-taxed at source. It’s a good way to penalise “dirty” goods and remove any competitive advantage the exporter gains from not paying for its pollution. Regions across the world are trying to figure out the best way – how, when, if at all - to roll them out. But Joseph Shapiro, writing for the Energy Institute at Haas, points out that the … [Read more...]
100% renewables by 2050: a technology, market, system, business model toolset for your nation
A growing number of countries are announcing increasingly ambitious renewable energy targets. But how do you deliver the results? IRENA’s Elena Ocenic explains that they have developed a toolset for countries to plot their unique pathway to success. Those tools range widely across technology, market design and regulation, system operation practices, and business models. The article lists the tools, and runs through some notable successes. Ocenic … [Read more...]
More nuclear means more waste disposal: the options, science, engineering
Public concern about nuclear power goes beyond an accident at a live plant. What do we do with the nuclear waste? If nuclear is to grow to become a major replacement for oil and gas the question must be answered. James Conca reviews the different methods that have been seriously considered: shooting it into space, burying it in deep sea trenches or under ice sheets, transmutation, or simply digging it even deeper underground. … [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...]
