Exelon Threatens to Close 2 Nuclear Plants as Battle Over State Subsidies Looms

GreenTechMedia

Exelon is following through with a threat to close two of its Illinois nuclear power plants by next year unless it receives state support to boost their financial viability, a move that could undermine the state's carbon-free electricity goals. Both states have aggressive zero-carbon energy policies.

Renewables overtake fossil fuels in 2020 as Britain's power grid enjoys 'greenest year' yet

Business Green

But Imperial College London analysis warns emerging technologies and negative emission power plants are likely to be needed to unlock full decarbonisation of the grid. Nuclear power, meanwhile, provided 17.5 per cent of Britain's power last year, while imports accounted for just under seven per cent.

Negative emissions under a net zero target: the controversies and pitfalls

Business Green

Josh Burke at LSE's Grantham Research Institute navigates the costs, opportunities, advantages and disadvantages of different carbon capture and negative emissions technologies. Net negative emissions are achieved when gross negative emissions match or exceed gross positive emissions. Why negative emissions?

A national home energy efficiency drive could save six nuclear reactors' worth of energy

Business Green

Improving the thermal performance of UK homes could deliver climate and energy security at a fraction of the cost of nuclear power, argues Kingspan's Rita Singh. However, the negative impacts of continued North Sea exploration could be felt for decades or even centuries. The answer is good, old-fashioned energy efficiency.

The story of how Britain's energy transition could unfold, told in 10 charts

Business Green

From 2047 onwards, the energy system could then become net negative, absorbing more emissions than it produces through a mix of carbon capture technologies and solutions, which operate on both a standalone basis and while attached to power stations. Systems thinking is critical to delivering a low-carbon economy.
