Uranium fission provides reliable heat from reactions that are six orders of magnitude (powers of ten) more energy dense than the combustion reactions used to produce energy from coal, oil and natural gas.

That has come courtesy of its association with conventional natural gas - which produces much less CO2 on combustion than coal and oil, and which is often touted as a «clean» fuel.

But a natural cycle of change in the North Atlantic may for the time being have countered the consequences of human combustion of fossil fuels, the rise of greenhouse gases and other impacts in the Arctic.

At the heart of both studies is a deeper concern about the response of the natural world to human - induced change, in the destruction of habitat, the loss of the plants, birds, insects, mammals, amphibians and reptiles that depend on habitat, and in the steady increase in atmospheric levels of greenhouse gases, as a consequence of profligate combustion of fossil fuels.

A conventional natural gas combustion turbine of the required size might require approximately $ 195 million in overnight capital costs (given the cost assumptions used in EIA's Annual Energy Outlook).
