When Prime Minister Theresa May went to Brussels to hand in her 'Article 50' Brexit notice, she was also pursuing a separate, covert objective, writes Zachary Davies Boren. Leaked papers show that the UK was lobbying to gut new EU rules and targets on renewable energy and energy efficiency - even though they will only come into force after Brexit.
A huge raft of environmental reforms is promised in the Labour Party's draft manifesto, writes Oliver Tickell. Among the highlights: a ban on fracking; a clean energy policy based on renewables and efficiency; no commitment to new nuclear power; to meet our Paris Agreement obligations on climate; to give companies a legal obligation to protect the environment; to retain all EU environment laws post-Brexit; and multilateral nuclear disarmament.
The UK's abject failure to implement national and EU laws on energy efficiency in buildings is a disgrace, writes Andrew Warren, and one that is costing us dear in higher fuel bills now and for long into the future, while adding to air pollution and climate change.
The UK's 'Green Deal' energy efficiency scheme was a massive failure, writes Sue Roberts. But few knew just how bad until the NAO's report - which reveals that its main effect was to line the pockets of the Big Six energy companies, load the public with expensive loans, create a tangle of red tape, and engineer the collapse of the UK's nascent energy efficiency sector.
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.
As temperatures soar in the Persian Gulf, modern buildings rely on energy-guzzling air-conditioning to maintain tolerable temperatures, writes Amin Al-Habaibeh. But traditional buildings stay cool passively using shade; wind and thermally driven ventilation; and naturally insulating, reflective materials. For a sustainable future, modern architects must revive the ancient knowledge.
Fuel poverty is a complex problem with many causes, writes Mari Martiskainen, but it is also a deadly one for some 25,000 thousand people every year. And there is one surprisingly simple solution: a huge upgrade in the energy efficiency of our housing stock.
It's a fair question, writes Doug Parr, but one to which we are getting no answers - the government is keeping its sums and energy models secret. It looks as if the energy department, DECC, is making things up as it goes along to justify its pro-nuclear, anti-efficiency and anti-renewables policies. And when it all goes disastrously wrong, who will end up paying for the mess? We will.
The Green Deal was expensive, bureaucratic, complex, inefficient and so badly designed it could have been set up to fail, writes Sue Roberts. Yet it was the UK's only national home insulation scheme and its intentions were sound. What it needed was rethink and reform, not scrapping - and with it gone, there's a huge gap that desperately needs to be filled.
There is huge untapped potential in the green economy to create millions of decent jobs, writes Jean Lambert - but only if lessons are learned from the Government's flawed, now scrapped, Green Deal. Lesson one: we desperately need a well-funded, ambitious replacement.
With the US, China, Germany and other countries firmly fixing their aim on a low carbon, renewable energy future, the UK government has chosen precisely the opposite track, write Noam Bergman, Lee Stapleton & Mari Martiskainen. Its mission to destroy wind and solar power, undercut energy efficiency and boost nuclear power and fracking threatens serious, lasting damage.
The UK Government has ditched the requirement for new homes to be 'zero carbon' from April 2016, writes Gordon Walker. With builders already geared up to meet the challenge, this needless reversal will raise energy bills and carbon emissions for a century or more to come, and send out all the wrong signals for the Paris climate talks.
Energy efficiency in office buildings struggles to gain the attention of top management, writes John Alker - because energy is too cheap to really matter. But with 90% of operating costs spent on staff, show that green building design makes employees happier and more productive, and you're really onto something ...
The Government has gutted its 'zero carbon home' standard - builders will be able to 'zero the carbon' through an offsetting scheme - rather than by installing more insulation, or renewable technologies like solar PV or solar water heating.
As the warmth of Christmas fades and winter proper sets in, Roland Ennos shares his tips for keeping warm in winter without spending a fortune on fuel. Simple, low-cost measures include closing curtains and blinds at night, leaning sheets of cardboard against cold outside walls, and and exploiting the insulating power of books.
As we embark on our final splurge of Christmas shopping, spare a thought for all those heaters blasting hot air in customers' faces, set above wide open doors. Jeannie Dawkins says the waste of energy is a national disgrace that must be ended!
A hub of invention, why can't the automobile industry get a handle on low-carbon cars? The answer's in the profit margins - which is why the credit crunch offers hope for the future, says Harriet Williams
