Wind and solar energy production are growing faster in the United States than any other source of electricity, and falling prices are making them more competitive with fossil fuel-driven electricity. Meanwhile, natural gas has surpassed coal as the prime fuel for power plants. Those trends helped drive down U.S. greenhouse gas emissions in 2017 to their lowest level since 1991, according to a report for the Business Council on Sustainable Energy.
That’s good news for anyone concerned about climate change. The shift to renewable energy is a key part of the global effort to reduce emissions of carbon dioxide and other earth-warming gases and slow down climate change by reducing our dependence on fossil fuels. But critics argue that this growth wouldn’t be possible without financial support from the government. How much do renewables actually need tax breaks and other subsides?

In Utuado, a town in the hills of central Puerto Rico, “very little works.” That’s what Delsie Gandia, a resident, told me several days ago via email during a rare opening when she could connect to the internet.
Since Hurricane Maria’s 150-plus mph winds scoured the island into a mass of rubble and smashed infrastructure on Sept. 20, residents have been showering in the rain and washing clothes by hand with spring water, she said. Electricity had been restored to Utuado proper, but, said Gandia, “As I write, we have been plunged in darkness once again.” Roads are washed out or blocked by debris; damage to the local communications tower and unreliable power hampers phone and internet services. Many people were cut off from relief, emergency health care and other services. Utuado’s mayor, whose rural home was destroyed in the storm, hacked his way into town with a machete, she was told.
“My impression was that all systems collapsed,” she wrote. “The government simply couldn’t cope.” (Gandia, an economist and a relative of mine, has studied the economic and environmental impacts of global warming since the 1970s.)
