NEW YORK (AP) - If the nation is to meet President Joe Biden's goal of cutting America's greenhouse gas emissions in half by the end of the decade, it will have to undertake a vast transformation toward renewable energy.
And to achieve that, the near-impossible will be required: A broad network of transmission lines will have to be built to carry solar and wind power across the continent to deliver electricity to homes and businesses - something the administration envisions accomplishing by 2035.
What's more, utility-scale batteries on a widespread scale, to store renewable energy for peak-use periods, would be needed.
The financial and technological tasks of linking cleaner power sources to an aging electric grid pummeled by climate change are daunting enough. Add to them the legal fights that states and localities will likely mount to fight the build-outs of transmission lines in their areas, and the challenges become extraordinary.
