Cheaper than coal: IRENA’s comprehensive report on cost declines, all renewables categories

by

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

by

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

by , and

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

by

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

by

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

by

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

by and

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...]

French government study: 95% renewable power mix cheaper than nuclear and gas

by

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

by

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)

by

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

by

At a “business booster” event in Barcelona, sixty European cleantech startups supported by KIC InnoEnergy, presented themselves to the world. They offered an impressive variety of new technologies and market innovations, ranging from new storage devices and solar chips to energy saving techniques, financing models and consumer engagement platforms. In this article we present to you some of the gamechangers of our future energy system – all made … [Read more...]

South Australia's renewable energy future

by

South Australia made headlines around the world when it was announced that the state had been powered by 100% renewable energy for an entire working day. Commentators took it as a proof that a fully renewable future is possible. South Australia, writes Jack Baldwin of the South Australian news service The Lead, demonstrates to the world the benefits of renewable energy. According to Baldwin, there are signs the rest of the country will follow, … [Read more...]

Brussels reveals: public support for renewables hardly different from non-renewables

by

For the first time ever, the EU Commission has mapped out how much public money flows to the energy sector in Europe and where it goes. According to a new report prepared by consultancy Ecofys, Europe spent €113 billion on energy subsidies in 2012. Remarkably, public support for coal is equal to that of onshore wind and total support for renewables is not much higher than for non-renewables. Also remarkably, the estimated “levelised costs” for … [Read more...]
