By “offsetting” fossil electricity consumed at one data centre through buying green power from somewhere else, Google has been 100% renewable since 2017. But offsetting always has its flaws. In this case, 40% of Google’s actual power still comes from fossil fuels. Google’s new plan, to be 100% green 24/7 straight off the local grid, is designed to solve that. It will also send market signals to increase clean capacity locally, not just where you … [Read more...]
German Geothermal: from 1.2TWh to 100TWh by 2050?
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...]
2019-2024: competitive auctions will launch over 2/3rds of utility-scale renewables, says IEA
Government support for new utility-scale capacity is being replaced with competitive auctions, the surest sign that the commercial appetite for renewables - particularly solar PV and onshore wind - is growing strong. This article by the IEA pulls out the essential numbers from their annual Renewables 2019 report (their 5-year market analysis and forecast for renewable energy and technologies in the electricity, heat and transport sectors). The … [Read more...]
Cheaper than coal: IRENA’s comprehensive report on cost declines, all renewables categories
The International Renewable Energy Agency’s (IRENA) latest report Renewable Power Generation Costs in 2018 details the global weighted-average levelised cost of electricity (LCOE) for all commercially available renewable technologies. It states that renewables are already the lowest-cost source of new power generation in many parts of the world today. By as soon as 2020, onshore wind and solar PV will join hydropower in consistently offering a … [Read more...]
Kenya, Bangladesh: Environmental rulings stall coal plans. So should the economics
The construction of two coal-fired power plants has been stalled in Kenya by the Kenyan courts and in Bangladesh by UNESCO, both for environmental reasons. It’s an opportunity for the two countries to also recognise the purely commercial reasons to go for renewables, says Simon Nicholas of IEEFA. While most of Asia has been powering ahead with renewables, Bangladesh has been lagging behind. But a continued rollout of renewable energy will quickly … [Read more...]
36bn GWh: the “limitless” Geothermal from old UK coal mines
The Earth gets hotter by 2.5C to 3.5C with each 100m depth. It’s what makes geothermal energy possible, anywhere. In the UK geothermal could meet the nation’s heat demands for at least 100 years, say Jon Gluyas, Andrew Crossland and Charlotte Adams of the Durham Energy Institute. Properly managed it could last indefinitely. Given that heat does not travel well, geothermal must be developed locally. Fortunately, accessible heat lies beneath or … [Read more...]
EXCLUSIVE: Geothermal could represent a far bigger share of renewables
The IEA says geothermal energy could account for only 3.5% of annual global electricity production and 3.9% of energy for heat (excluding ground source heat pumps) by 2050. But is this down to short term thinking? Geothermal could make a much bigger contribution to renewables, provided it is put onto the fast track like wind and solar, says Alexander Richter, President of the International Geothermal Association. … [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...]
Wind top new power capacity source in Europe
In 2015 12,800 MW of new wind power capacity was installed in the EU, an increase of 6.3% over 2014, and more than any other form of power generation, according to recent new figures from the European Wind Energy Association (EWEA). Wind power accounted for over 44% of total power capacity installations in the EU last year. … [Read more...]
The new Polish government’s energy policy: expect more State, less market
The new Polish government will not just resist ambitious EU climate targets, it will also increase the role of the State in the energy sector, write researchers Kacper Szulecki (University of Oslo) and Andrzej Ancygier (Climate Analytics) . The conservative Law and Justice Party that has been swept into power intends to create a Ministry of Energy, which will take control of the major Polish energy companies, note the authors. The likely new … [Read more...]
New clean energy investment falls in first quarter 2015
New investment in the global clean energy sector totalled $61.0 billion in Q1 15, a 14% decrease on Q4 14 ($71.3 billion) and a 5% decrease on the corresponding quarter in 2014 ($64.4 billion). … [Read more...]
French government study: 95% renewable power mix cheaper than nuclear and gas
A new French government study shows that the cost to the French consumer of a 100% renewable scenario is more or less equal to a scenario close to today’s, with only 40% renewables. It is yet another instance of leading energy experts asserting that a 100% renewable future is possible, writes Terje Osmundsen, Senior Vice-President of Norwegian independent solar power producer Scatec Solar. … [Read more...]
Vindication for Allan Hoffman: the US has turned the corner on renewables
It has been 37 years since Dr Allan Hoffman gave President Jimmy Carter the plan that could have started America’s renewable revolution. The idea was shelved after Reagan was elected. Hoffman waited, as administration after administration ignored the potential, until Barack Obama was elected. The retired senior Department of Energy executive views the growth of US renewables during 2014 as a vindication of what he and his colleagues saw decades … [Read more...]
Why Google gave up on renewables (hint: because they don’t know much about energy)
The two scientists responsible for Google’s failed attempt to launch a renewable energy revolution have written an article explaining what, according to them, went wrong with their project. They have come to the conclusion that fighting climate change with today’s renewable energy technologies won’t work – but they present no evidence for it, writes Energy Post editor Karel Beckman. … [Read more...]
Cleantech innovation in Europe: here are the gamechangers of the future
