Dr. Kara Kockelman: The future of motorized travel

…and that very fast current movement. But all our vehicles can be set to charge at whatever time of night we want. And we can have a smart communication with the grid on a second by second or sub-second level to sense when renewables are high. There can be communications to help those battery vehicles…

Theresa Pistochini: Home heat pumps and indoor air quality

…on site emissions. Now the discussion becomes what did we do to create that electricity, and what was the global warming impact associated with that. And that’s changing rapidly over time as the way we generate electricity is evolving with the increase of renewables on the grid. And the other tricky thing is that when…

Climate change: rising to the challenge

…speak a certain way. MILES O’BRIEN:Good. So let it rip, will you? So Justin, you’re a state employee, and your boss, the governor, is very much into renewables, but not so much into believing that climate change is – has a human component to it. Does that affect in any way how you do your…

…transportation (primarily cars and trucks burning gasoline) and for generating electricity (primarily burning natural gas and coal). Fossil fuels are the primary means of producing electricity in the United States. Natural gas (38%) and coal (24%) are the major fuels for generating electricity. Other major sources are nuclear power (20%) and renewables including hydropower (7%),…

The climate-energy nexus

…meaning the energy they produce must sometimes be stored for later use. Burning natural gas to generate electricity produces about 60% less CO2 than using coal, making gas an imperfect but useful “bridge fuel” to help reduce CO2 emissions during a transition to renewables. Renewable energy sources such as hydropower, solar, and wind cannot address…

COP26: U.N. climate summit in Glasgow

…cost, while also a decarbonized grid, with renewables integration, is essential to maximize the benefits accrued on the road to net zero. Significant investment is needed by governments in charging infrastructure to enable sooner adoption of electric cars by the mass market. Carbon reduction programs should be carefully devised by governments so that they can…
