With oil prices remaining low, the world's oil industry is facing bleak years ahead, writes Paul Brown. The global push to decarbonise the economy, combined with surging renewable energy and the trend to more efficient and electric vehicles, is denting investor confidence and pointing to the shrinking away of a once mighty and profitable industry.
The nuclear industry faces an uncertain future as the reactor building boom is struck by unexpected costs, serious technical problems, and long, expensive delays, writes Paul Brown. Meanwhile renewables like wind and solar are offering investors an enviable combination of falling cost, low risk, fast build times, predictable returns and minimal long term liabilities.
A legacy of lies and covered-up accidents has left nuclear energy with a serious credibility gap, writes Paul Brown. But poor safety is only the beginning of the industry's problems. With 'new improved' reactor designs all running late and way over budget, any nuclear revival can only be sustained at massive, unaffordable taxpayer cost.
Nuclear giant EDF could be heading towards bankruptcy, writes Paul Brown, as it faces a perfect storm of under-estimated costs for decommissioning, waste disposal and Hinkley C. Meanwhile income from power sales is lagging behind costs, and 17 of its reactors are off-line for safety tests. Yet French and UK governments are turning a blind eye to the looming financial crisis.
Following the vote to leave the EU, the UK's energy and climate change policy faces major challenges, writes Paul Brown, with new nuclear power and a third London runway at Heathrow runway looking like the first casualties.
MPs today grilled EDF Energy supremo Vincent de Rivaz over the troubled Hinkley C nuclear plant in Somerset. He insisted that the project was definitely going ahead - but refused to say when the 'final investment decision' was due. Confused? Bewildered? Frustrated? So were the MPs.
Nuclear giant EDF can't afford to write off the £2 billion sunk into the Hinkley C nuclear plant, write Paul Brown & Oliver Tickell. So its cunning plan is to turn it into a 'nuclear zombie' - officially a live project, but actually stone cold dead - until EDF can find a way out of the hole it has dug itself into.
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.
As worldwide stocks of plutonium increase, lightly-armed British ships are about to carry an initial 330kg of the nuclear bomb metal for 'safekeeping' in the US, writes Paul Brown. But it's only the tip of a global 'plutonium mountain' of hundreds of tonnes nuclear power's most hazardous waste product.
Renewable energy could supply Russia and Central Asian countries with 100% of their electricity needs by 2030, writes Paul Brown - and cut costs significantly compared to nuclear power and CO2-abated fossil fuels.
'Pay up or there's no deal', a coalition of 134 developing nations have warned the rich industrial countries at COP21 in Paris - the ones that caused the climate problem in the first place. As Paul Brown writes, much more than the $64 billion so far pledged will be needed to get them on board.
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.
Increasingly mild winters have caused an abundance of acorns and beech nuts in Europe's woodlands, writes Paul Brown, triggering a wild boar population explosion - just one of the effects of warming climate on wildlife populations.
Engineers in Norway aim to put their mighty hydroelectric dams to a new purpose, writes Paul Brown - as giant batteries to store up surplus power from wind and sun across Europe, and put it back in the grid when generation falls off or demand is strong.
Sea level rise, storm surges and bursting dams all pose an increasing danger to nuclear power stations across the world, writes Paul Brown, as the long term risk posed by climate change combines with chance events from extreme weather events to earthquakes.
A serious flaw in the steel reactor vessel of a nuclear plant under construction in France raises safety fears for the EPR design, write Paul Brown & Oliver Tickell - and casts a dark shadow over the UK's troubled Hinkley C nuclear project.
Biofuels are controversial because they are often produced from food crops or grown on farmland, writes Paul Brown, creating extra pressure on land and forests. But a common algae found in abundance around coastlines and clogging up beaches may be the answer.
Scandinavian inventors are hoping that efficient new waves power technologies will for the first time make the sector competitive with other renewable energy sources, writes Paul Brown - opening up a massive new clean energy resource around the world.
The charity SolarAid has just celebrated 1.5 million small solar lighting installations in Africa, writes Paul Brown - an important milestone on its mission to get solar lighting into all of Africa's homes by 2020, and see out dangerous, polluting kerosene lamps.
China has now overtaken the European Union as the largest new market for solar power, writes Paul Brown - as solar PV becomes one of the world's fastest growing industries - and one that's sure to keep on getting cheaper!
Charlatans, or planetary saviours? Post-Paris views on the nuclear industry suggest few experts believe it will bring closer a world rid of fossil fuels, writes Paul Brown. Despite the best efforts of nuclear lobbyists, no revival is due any time soon.
Governments are still spending billions on nuclear research, writes Paul Brown - but 2015 looks like being an unhappy year for the industry as it continues to shrink while renewables grow, amid massive delays and cost over-runs.
After a second extra day of climate talks in Lima, an agreement has been cobbled together. Deadlines have been set for the world to come up with plans to curb emissions and adapt to climate change - but has been no progress on the key divisive issues, and the prospects of an effective mew treaty in Paris next year remain remote.
