Dong Energy has set a record low price for an offshore wind farm in the Netherlands. According to energy expert Mike Parr, the Dutch achieved this result thanks to their tendering model – following the Danes – offering a shovel-ready project to operators. UK wind farms are much more expensive because the UK lets operators carry out preparatory work by themselves. In any case, the future for offshore wind now looks bright. … [Read more...]
How solar growth will wreck the economics of existing power markets
Continued solar growth could lead to significant decreases in wholesale electricity prices during most peak hours, writes Alex Gilbert, cofounder of US-based energy research platform Spark Library, in an article analysing the effects of solar power on electricity markets. While lower wholesale prices can impact solar’s growth they will also hurt other energy sources, particularly coal and nuclear but also natural gas and energy efficiency. … [Read more...]
Germany sets a new solar storage record
With the most photovoltaic capacity of any country in Europe, Germany has begun to store its excess solar power to enhance local usage. Last year, 41% of all new solar installations were equipped with backup batteries, a world record. Although home storage may only have a limited role to play in Germany due to a highly reliable grid, globally the German initiative could provide great benefits, for example in counterbalancing the predicted … [Read more...]
DNV GL sees solar power revolution, acquires Spanish solar monitoring company
DNV GL, one the world largest independent energy consultancies, has strengthened its position in the solar power sector with the acquisition of GreenPowerMonitor, a leading provider of solar monitoring, control and asset management systems. The CEO’s of DNV GL- Energy, Ditlev Engel, and GreenPowerMonitor, Juan Carlos ArĂ©valo, expect the solar market to triple and projects to become ever bigger, they tell Energy Post. With 150 solar experts, the … [Read more...]
How to support renewables in Europe
The development of green energy in the EU is taking place in a highly inefficient way, with much of the renewable energy sources built in the least productive locations, writes Jakub Kucera, economic analyst at RSJ, a Prague-based investment company. To address this problem, an EU-wide support scheme could be envisaged, but that also has many drawbacks, notes Kucera. He suggests that a combination of an EU-wide scheme with national support … [Read more...]
How to build a wind turbine
In case you thought that building a wind turbine is a fairly simple matter, this video from Siemens USA gives you an idea of what is involved. A lot of concrete, for one thing. We wanted to share this with our readers. We hope you like it. … [Read more...]
Dutch research project shows costs offshore wind can be reduced 40% in ten years
The Dutch research programme FLOW (Far and Large Offshore Wind energy) shows that a well-coordinated approach between industry, knowledge institutes and government can achieve 40% cost reduction in ten years in the offshore wind sector. In about ten to fifteen years, offshore wind should be able to manage without subsidies. … [Read more...]
A fundamental transformation: “renewables win race on costs”
The cost of wind and solar power will continue to fall massively over the next 25 years, bringing about a fundamental transformation of the global electricity sector, according to new reports from Bloomberg New Energy Finance (BNEF) and the International Renewable Energy Agency (IRENA). Electric cars will boom, cheap batteries will be everywhere and there will no Golden Age of Gas, despite continued low gas prices, BNEF predicts. … [Read more...]
Energy crops have been a major flop with farmers – here’s why
In only a few years, biomass has become a major UK power source, supplying 3% of the total electricity supply. However, despite government incentives, UK farmers are largely unwilling to grow the feedstock for the biomass plants. Most of it has to be imported. Charles Warren, Senior Lecturer Geography and Sustainable Development at the University of St. Andrews, tried to find out why – and came to some very instructive conclusions. Courtesy The … [Read more...]
Europe can retrieve its lost clean energy leadership by moving away from subsidizing renewables
Europe can win back its lost clean energy leadership by moving away from subsidy-powered renewables, writes Christopher Burghardt, Vice-President Business Development Europe at First Solar and a member of the Board of Directors of Solar Power Europe. Rather than subsidizing renewables, Burghardt argues, Europe should stimulate utility-scale energy production by independent power producers, just as other markets around the world are … [Read more...]
Renewable energy versus nuclear: dispelling the myths
Don’t believe the spurious claims of nuclear shills constantly putting down renewables, writes Mark Diesendorf, Associate Professor of Interdisciplinary Environmental Studies at UNSW Australia. Clean, safe renewable energy technologies have the potential to supply 100% of the world’s electricity demand – but the first hurdle is to refute the deliberately misleading myths designed to promote the politically powerful but ultimately doomed nuclear … [Read more...]
Renewables in China and India: two Asian giants struggling with inflexible power system operations
China and India are building huge amounts of solar and wind power, but a lot of this capacity is wasted as it cannot be integrated into the grid. In China the problems stem mostly from rigid planning processes and compensation systems. In India, the stumbling block is state-owned distribution operators that have an incentive not to increase access to electricity. In both countries, reforms are contemplated but will be difficult to achieve. This … [Read more...]
Can we save the algae biofuel industry?
Over the last decade or so, energy companies, including the likes of Shell and ExxonMobil, have invested large amounts of money in algal biofuels, only to find that the economics didn’t make sense, writes Christian Ridley, Research Associate in Plant Biotechnology at the University of Cambridge. However, according to Ridley, there still is a way forward for the industry, if the production of biodiesel from algae can be combined with production of … [Read more...]
Oil: not yesterday’s fuel – just yet
The new hype is to say that the end of the oil age is near. In the long run, the importance of oil will diminish, write Peter Simon Vargha, Chief Economist at  Hungarian oil and gas company MOL and his colleague Csaba Pogonyi, but before that some good years for oil are likely. Just as high prices reduced the likely future demand for oil, low prices will probably prolong its use. … [Read more...]
Why both incumbents and disruptors are struggling in the new energy market
The energy world is changing fast. Investments into renewable energy are outpacing investments into conventional energy. The incumbents, unused to this pace of change and tied down by large asset bases and long-term investment strategies, are struggling. But they are not the only ones. The disruptors are also finding it difficult to build new energy businesses. In fact, many of the companies that will in the end be able to benefit from the energy … [Read more...]
