The transition to renewable energy is accompanied by the widespread use of power electronics, such as inverters, which require a whole new way of testing smart equipment, says Theo Bosma, Program Director Power Systems & Electrification at DNV GL, one of the largest technical consultancies in the world. According to Bosma, the new power electronics are not adequately tested at the moment. “New technologies such as solar, wind, batteries and … [Read more...]
Here’s how to build 100% clean renewable energy in the US before 2040
There really is a feasible way to build our way out of the climate crisis in time to avoid the worst effects of global warming, writes Tom Solomon of 350 New Mexico. We do it by rapidly replacing all fossil fuel-based energy with renewable energy built with current technology, installed in a smart grid. We pay for it without damaging the economy and actually save money vs. our current reliance on fossil fuels. The ‘side benefits’ include cleaner … [Read more...]
The Energiewende is running up against its limits
German transmission system operator Tennet recently announced an 80% increase in its transmission fees because of the high construction costs of new power lines to accommodate renewable energy. A study of the Düsseldorf Institute for Competition Economics found that by 2025 costs of the Energiewende could exceed €25,000 for an average four-person household. Jeffrey Michel concludes that the Energiewende is running up against its limits – but may … [Read more...]
To keep European offshore wind world-leading, we need an industrial policy
To retain the global lead European companies have in offshore wind, the EU should develop an industrial policy that will guarantee a steady pipeline of projects, writes independent energy expert Mike Parr. This would ensure continued investment by companies in cost reduction and technology improvements. Failure to do so could mean the offshore wind sector would suffer the same fate as the European solar PV industry. … [Read more...]
The economic and moral bankruptcy of UK energy policy
With its choice for Hinkley Point C - a £100 billion boondoggle – its enthusiastic support for expensive and environmentally harmful fracking, and its relentless attack on renewable energy, the UK government’s energy policy is both morally and economically bankrupt, write Peter Strachan, Professor of Energy Policy at the Robert Gordon University, and Alex Russell, Professor and Chair of the Oil Industry Finance Committee. Westminster must … [Read more...]
South Africa’s rapid energy transition derails its giant nuclear and coal projects
South Africa shows how quick an energy transition can be. In four years, the country’s renewable energy program has mushroomed, while the building of coal power stations and the planning of a $50-$100 billion nuclear power project have come to a grinding halt. Recent events, however, have raised some uncertainty for renewables, writes South African based science writer Leonie Joubert. Article courtesy of the Energy Transition blog. … [Read more...]
IEA sees “major shift” – but not major enough
“A major shift in investment towards low-carbon sources of power generation is underway”, according to a first-ever detailed analysis of investment across the global energy system from the International Energy Agency (IEA). Yet, in non-OECD countries, “investment in conventional generation remains strong”, with over 75 GW of coal-fired power plants starting operation in 2015 in “developing Asia” – “as much as all renewable capacity additions in … [Read more...]
China’s continuing renewable energy revolution – can it save the world?
China has made strategic choices favouring renewables over fossil fuels that are still not widely understood or appreciated, writes John A. Mathews, Professor of Management, Macquarie University, Australia. In this article he gives an overview of the latest trends in Chinese eletric power generation, which shows that the system is still "greening" faster than it is becoming black. But whether it is changing fast enough to save the world, is still … [Read more...]
Paris deal, rapid transition means deepening doldrums for energy incumbents
Even as the earth is heating up, established oil, gas and nuclear companies are increasingly feeling the heat of the energy transition, writes famous author and entrepreneur Jeremy Leggett. Signs are everywhere that the fossil fuels game is almost up. This article was republished from Leggett's blog. … [Read more...]
Britain is only just beginning to exploit its vast resources of offshore wind
A new study finds that the UK can install up to 675 GW of economically feasible offshore wind, writes Simon Watson, Professor of Wind Energy at Loughborough University. This could provide more than six times the UK’s present national electricity demand. As current capacity is only 5 GW, there is ample room for growth. Yet there are also still major challenges to overcome. Article courtesy of The Conversation. … [Read more...]
A reality check on renewable energy potential
On a global level, the potential for renewable energy is more than sufficient, writes researcher Schalk Cloete. However, on a regional level, this is not the case, especially in developing Asia and Africa. Renewable energy technology forcing in these regions can have serious socio-economic consequences. … [Read more...]
The hydrogen economy is much nearer than we think
For over 30 years promoters of green energy have proclaimed the hydrogen economy is around the corner. Now this could finally become true. While some energy experts claim that hydrogen from renewable energy is prohibitively expensive, companies like ITM in the UK are proving in the market that this technology is already competitive. They produce hydrogen for use in cars and in the form of power-to-gas to be used in the gas network. Energy … [Read more...]
Interview Sir John Scarlett, advisor Statoil, ex-head MI6: “The role of old-fashioned geopolitics will become less important in energy”
Thanks to new energy policies, technologies and market trends the potential to use energy for political purposes has decreased in recent years, says Sir John Scarlett, former Chief of the Secret Intelligence Service MI6 and now Chairman of the Strategy Advisory Council at Statoil, in an interview with Energy Post. At the same time he notes that instability in North Africa, the Middle East and Eastern Europe has grown and energy security should … [Read more...]
Ukrainian crisis can be solved – with an Energiewende
A Ukrainian Energiewende could go a long way to resolving the current geopolitical crisis around the country, writes Oleg Savitsky of the National Ecological Centre of Ukraine in a new report for the Succow Stiftung. According to Savitsky, it would reduce Ukraine’s dependence on Russian gas and uranium as well as on coal from the breakaway regions, while at the same time reducing pollution, greenhouse gas emissions and the risk of a nuclear … [Read more...]
Offshore wind: Europe far ahead, Siemens largest by far
The number of new offshore wind installations in Europe went down sharply in the first half of 2016, but investment grew to a record €14 billion, promising higher growth in the coming years. Siemens installed all 114 new turbines in Europe in 2016 and has a global market share of 64%, according to new reports from WindEurope and PlanetOS. … [Read more...]
