With the Midlands shivering over the weekend and the country rumoured to be on the brink of a "really bad winter", the question of nuclear power has arisen again.
Many companies have complained for months about rising energy prices; it will only take a really cold snap for oil and gas consumption to surge and trigger massive price rises.
Amid this bleak backdrop, business leaders will today urge the Government to reach a decision about the future of the atomic option.
No, it's not about whether we should have more nuclear submarines to menace AK-47-wielding terrorists, but whether, where, when and how many power stations are we going to build.
Ministers will be pressed by the CBI to draw up a coherent energy policy as a matter of urgency, including a decision on whether to back a new generation of nuclear power stations.
Meanwhile, in a separate report, the Engineering Employers' Federation (EEF) said the Government should back replacement nuclear build, adding that it could be the most competitive form of energy.
The CBI said a third of the UK's generating capacity, much of it nuclear, had to be replaced by 2020.
Director General Sir Digby Jones said: "A decision on the future of nuclear power has been allowed to drift too long.
"Nuclear's position as a reliable, low-carbon energy source is without doubt, but understandable concerns exist about costs and waste.
"Without a coherent and integrated energy policy there is a risk that the billions of investment required will not come at the right time or at the most efficient cost.
"The opportunity must now be seized."
The business group said the Government should commission a study on the economics of nuclear compared with other forms of power.
The EEF warned that the competitiveness of the power industry was threatened by a more expensive and less reliable supply of energy unless the Government finalised a long-term strategy.
Director General Martin Temple said: "Energy is now right at the top of the agenda and there is no time to lose in putting in place a long-term strategy that will provide a competitive, reliable and secure supply and generate significant reduction in emissions." But most people still need to be convinced with one poll saying 59 per cent of people are opposed to building more nuclear power stations in the UK.
There still remains the risk of a major accident, and it can't exactly be turned off when finished with it, and what do we do with the waste?
The counter point is nuclear may ultimately be cleaner, more efficient and the most cost effective option in a world of declining fossil fuels. France derives 75 per cent of its energy from nuclear power, while fossil fuels can be used for other things apart from energy.
People are going to moan about it, but it could be the least bad option. Wind power alone isn't going to help that much, and people complain about that, too, messing up the countryside.
Just as long as we don't have a nuclear power station near my house . . .
