The government is due to announce a £250 million support package for 'small modular reactors' his week, just as the price of wind and solar power contracts fall 10% below UK wholesale prices. OLIVER TICKELL argues that the Britain's 'civilian' nuclear power expenditure is actually a camouflaged subsidy to the UK's Trident nuclear missile system.
The International Energy Agency's latest World Energy Outlook is calling for increased investment in new oil and gas, writes Oliver Tickell, while minimising the fast-growing and ever lower-cost contribution to world energy supply of renewables like wind and solar.
Onshore wind power is effective, hugely popular, and the UK's cheapest form of new power generation, writes Max Wakefield, already competing against gas turbines in prime locations. So why did Cameron's Government ban it? And what will it take to get Chancellor Philip Hammond to reverse that decision next week?
Hydrogen made from renewable electricity is already fuelling vehicles at affordable prices, writes DAVID THORPE. But now the 'green' fuel is set to go from niche to mainstream - powering not just cars, trucks and buses, but storing surplus renewable energy on sunny and windy days, then to be burnt in gas turbines or fuel cells to supply the grid with reliable power on demand.
Solar is already the cheapest available power across large swathes of the tropics, writes Chris Goodall - its cost down 99.7% since the early 70s. Soon it will be the cheapest electricity everywhere, providing clean, secure, affordable energy for all.
The cost of offshore wind power in the North Sea is 30% lower than that of new nuclear, writes Kieran Cooke - helped along by low oil and steel prices, reduced maintenance and mass production. By 2030 the sector is expected to supply 7% of Europe's electricity.
The renewable energy revolution is in full swing, writes Jeremy Leggett, with costs falling to new lows, deployment of wind and solar surging to unprecedented highs, and confidence ebbing away from fossil fuels. But global warming is also accelerating, with global temperature records broken every month for a year. Will the energy transition happen in time to avert catastrophe?
Critics of renewable energy sources like wind and solar claim that they are inefficient, unreliable and need to be backed up by coal and gas, writes David Elliott. But we have the technology to match green power supply and demand at affordable cost without fossil fuels - by deploying the 'smart grid', using 'green gas' made from surplus power, and raising energy efficiency.
The main claim used to justify nuclear is that it's the only low carbon power source that can supply 'reliable, baseload electricity', writes Mark Diesendorf - unlike wind and solar. But not only can renewables supply baseload power, they can do something far more valuable: supply power flexibly according to demand. Now nuclear power really is redundant.
If the UK really wants 3.2GW of 'baseload' power in Somerset, then the Hinkley C nuclear power station is not the only way, write Marie-Louise Heddrich, Thorsten Lenck and Carlos Perez Linkenheil. Wind power with 'wind to gas' plant and CCGT gas power stations could do the same - faster, cheaper, more flexibily, and at much lower technical and financial risk.
The ever-falling cost of renewable energy could leave investors in coal, gas and oil seriously out of pocket as demand for fossil fuels falls away, writes Paul Brown. In the wake of the Paris Agreement and shrinking markets in major importing countries, the smart money is moving into renewables.
Scientists say interstate energy 'highways' offer a simple approach to delivering low-cost electricity to where it’s needed throughout the US, writes Tim Radford. The best part? It's using clean, renewable energy sources, and it can be achieved in the near future using only existing, mature technologies.
As presidential contenders gather in Iowa for the beginning of the party selection season, they may have noticed a lot of wind turbines, writes Zachary Davies Boren. And if they have any sense, they will find only nice things to say about them. Wind supplies 30% of the state's power, more than any other US state, and Iowans are all for it. Ted Cruz, mind your words!
Floating wind turbines offer huge falls in the cost of offshore wind power, writes Paul Brown, and could be generating power in UK waters at well under the cost of new nuclear by 2020, provided adequate support.
The effect of wind and solar generation in the UK is to push down wholesale power prices, writes Oliver Tickell, taking over £1.5 billion off our bills in 2014 - that's 58% of the subsidies paid to renewable generators. Keep it up and the benefit will rise to over 100% of cost.
The government's decision to turn down the 1GW Navitus Bay offshore wind farm near the Isle of Wight sends a chilling message to developers: 'don't waste your time and money here!' The refusal of planning permission based on visual impact to a geological world heritage area is capricious and threatens to kill off an industry in which the UK has been - until now - the world leader.
A stones throw from where Cuadrilla lost its bid to develop a fracking operation in Lancashire, a solar farm has just won planning permission with widespread local support, writes Ben Lucas. However a 194-turbine offshore wind farm near the Isle of Wight has been refused planning consent.
This week Chancellor George Osborne told Parliament that the power from the planned Hinkley C nuclear plant would be cheaper than onshore wind, writes Doug Parr. That could be true on Planet Zog - but here on Earth the reverse is the case. Exactly what are Osborne and his Treasury mandarins smoking?
Solar PV costs have fallen by 75% over five years ago, writes Chris Goodall, making it the cheapest new power source for around half of the world's population. Now it's essential to keep incentives to drive demand for a few more years, and make it cheaper than fossil fuels everywhere.
The UK government is to cut support for domestic rooftop solar to 13% of current levels, with similar cuts for bigger systems, and end all support for small scale renewables by 2019. The likely result, and surely the intention, is to kill off the UK's solar industry altogether.
The success of the SNP and surveys carried out by DECC show that green energy is overwhelmingly popular, writes Keith Barnham. Labour's failure to support renewables and oppose nuclear power and fracking may have cost them the last election - but now, with the rise of Jeremy Corbyn there's a real chance for the party to put that right.
