nuclear power is a risky and expensive form of clean energy, but one that is important as we look to move away from fossil fuels. however, recent accidents and the rise of safer renewable energy have made this exceptional power source less attractive. write an article in 100-150 words about the pros and cons of nuclear power generation.

Answer:
As young people rightly demand real solutions to climate change, the question is not what to do — eliminate fossil fuels by 2050 — but how. Beyond decarbonizing today’s electric grid, we must use clean electricity to replace fossil fuels in transportation, industry and heating. We must provide for the fast-growing energy needs of poorer countries and extend the grid to a billion people who now lack electricity. And still more electricity will be needed to remove excess carbon dioxide from the atmosphere by midcentury.
Where will this gargantuan amount of carbon-free energy come from? The popular answer is renewables alone, but this is a fantasy. Wind and solar power are becoming cheaper, but they are not available around the clock, rain or shine, and batteries that could power entire cities for days or weeks show no sign of materializing any time soon. Today, renewables work only with fossil-fuel backup.
Germany, which went all-in for renewables, has seen little reduction in carbon emissions, and, according to our calculations, at Germany’s rate of adding clean energy relative to gross domestic product, it would take the world more than a century to decarbonize, even if the country wasn’t also retiring nuclear plants early. A few lucky countries with abundant hydroelectricity, like Norway and New Zealand, have decarbonized their electric grids, but their success cannot be scaled up elsewhere: The world’s best hydro sites are already dammed.
Small wonder that a growing response to these intimidating facts is, “We’re cooked.”
But we actually have proven models for rapid decarbonization with economic and energy growth: France and Sweden. They decarbonized their grids decades ago and now emit less than a tenth of the world average of carbon dioxide per kilowatt-hour. They remain among the world’s most pleasant places to live and enjoy much cheaper electricity than Germany to boot.
