Britain faces difficult choices about its future energy supplies yet every proposal meets strenuous, sometimes hostile, objections. For The Editors, a programme that sets out to ask challenging questions, I wanted to find out why everyone was so angry about energy.
Propose a new wind farm for some beautiful uplands one morning and you can guarantee a protest group furious at the ruined views will have formed by the afternoon.
The context for the green charges that David Cameron wants to roll back is the Climate Change Act. It was voted through almost unanimously back in 2008 - only five MPs objected - and this set the framework for deep cuts in greenhouse gases over the next few decades.
With this, Britain became the first country to have legally binding targets and the goal is to reduce emissions by 80% compared to 1990 levels.
How to keep the lights on at a price people can afford while cutting the greenhouse gases blamed for global warming - that's the triple challenge facing Britain.
This involves not only trying to close the gap between demand and supply as older power stations are closed down, but also finding ways of reducing household bills that have been rising fast, and at the same time meeting targets, enshrined in law, for the country to "decarbonise", to switch away from fossil fuels, for the sake of the future climate.
How do we decide what's worth saving and what we would happily see destroyed to make way for development? For The Editors, a programme which sets out to ask challenging questions, I asked what price, for example, for the White Cliffs of Dover?
Woven into the national fabric as a symbol of wartime defiance, the cliffs stand immortalised by the voice of Vera Lynn and images of soaring Spitfires.
Residents of Arizona have been mourning the 19 firefighters who were killed battling a ferocious wildfire last weekend. The Yarnell Hill Fire saw the biggest loss of firefighters' lives since the 9/11 attacks.
The road from Prescott to Yarnell would, in normal times, be a joy to drive along.
One of the first people we met near the scene of the fire was a utility worker who couldn't help crying - one of the 19 dead firefighters turned out to be the son of a friend. Another local man told me he had no idea if his house had been spared.
From behind a roadblock, we can watch a vast cloud of smoke rise and spread. Even from several miles away, flames are occasionally visible. Firefighting planes swoop through the haze. Searing heat, strong gusts of wind and the risk of lightning are keeping everyone on edge.
The sight of the Chancellor giving a speech at the Royal Society last November was a sign for some that the government does understand the value of science to a modern economy.
George Osborne talked of long-term commitments to building British leadership in everything from synthetic biology to regenerative medicine to energy storage. But the real test of political will comes down to hard cash. And the world of British science is worried that its pleas are not being heard clearly enough.
It takes the "right stuff" to withstand cosmic bursts of camera light and meteoric bombardments of questions, but Tim Peake is orbit-ready and passed the test of facing the massed media on Monday morning.
As Britain's first official, government-backed astronaut, his selection for a mission in late 2015 marks a pivotal moment.
Twenty years ago David visited the secret lab at Los Alamos that created the nuclear bomb and he's been fascinated by science and scientists ever since. His reports on research have taken him as far afield as the Antarctic ice-sheet, the Amazon rainforest and the depths of the Gulf of Mexico.
Since joining the BBC back in 1983, David has covered Northern Ireland, defence, Europe and world affairs. He is the author of three books.
His favourite memories include reporting from East Berlin during the fall of the Wall and exploring the tunnels of the Large Hadron Collider on a bike.
