Fossil fuels are still a large source of electricity, but California has made progress with renewables while keeping the lights on. The state recently hit a milestone: 100 days this year with 100% carbon-free, renewable electricity for at least a part of each day. The state notched the milestone while avoiding blackouts and emergency power reductions this year, even with the hottest July on record. That's according to Stanford University engineering Professor Mark Z. Jacobson. Energy experts say the progress is largely due to the substantial public and private investments in renewable energy. But California still has a long way to go to stop burning fossil fuels. Natural gas remains its single largest source of electricity.
The Department of Energy on Tuesday announced $2.2 billion in funding for eight projects across 18 states to strengthen the electrical grid against increasing extreme weather, advance the transition to cleaner electricity and meet a growing demand for power. The money will help build more than 600 miles of new transmission lines and upgrade about 400 miles of existing lines so that they can carry more current. Energy Secretary Jennifer Granholm said the funding is important because extreme weather events fueled by climate change are increasing, damaging towers and bringing down wires, causing power outages. The department says the investments will provide more reliable, affordable electricity for 56 million homes and businesses.
