BRUSSELS (AP) — A report issued Thursday says the European Union can cut its emissions of greenhouse gases dramatically by 2050 without spending any more money — and even, perhaps, saving a bit.

That estimate is based on an assessment that the new plants and equipment needed to switch to the generation of clean energy would cost more than continued reliance on fossil fuels, but that the clean energy itself would cost less.

Providing clean, renewable energy to the 1.4 billion people who are living without electricity is the No. 1 priority of the United Nations, the secretary general of the U.N. said during a visit Aug. 24 to the U.S. Department of Energy's National Renewable Energy Laboratory.
