. > >> joining us live is severn bornstein with uc, berkeley's ey berkeley's energy to do. earlier earlier in the spring, the state state public utilities commission warned that we might see these power outages, these rolling blackouts as we call them, now here we are. >> that is right. we are seeing a really bad heat wave that is bad, both because it will last r many days, longer than a typical a typical heat wave, also because it is very widespread. it extends all the way in the e, into the rocky mountains, and up and up to the north. this is the the sort of heat wave that can really cause problems. california imports about 25% of the electricity we use. it is harder to get power from those neighboring states when they are are also having a heat wave. >> so, how much of this current energy crunch is related to the state's transition to green power? >> it is certainly related to the fact that we are transitioning away from coal and and natural gas, and toward more more renewables in that, later in the day, as the sun sets, that is when we are starting to see the problem, r

and if you talk to anybody, any of the indendent energy experts like seven bornstein at úthe universityof california berkeley, you hear what the governor says, you talk to the independent system operator, we are in a transitional period where we're sifting very strongly to these renewable sources. solar, mainly, and also wind. and that builds in a very vulnerable time of day every time we have extreme heat. and that vulnerable time of day is late in the afternoon. this time of year, the solar starts to go down at 4:00, and -- >> because the sun is not out as much anymore, right? >> exactly. it's going down, and we have soaring energy demand at the same time, at that point of the day. so it's really a question of, you know, the robustness of the system, is trying to get through that time of day. and that's where these flex alert -- we are on our 10th straight day of flex alert for conversation. that's where that comes in, where energy conservation is being strongly encouraged right at that point of the day. >> but what about storing some of that solar energy? >> that's always been a big

several bornstein says the california power grid is better prepared for this type of event than it was a couple of years ago, and we're keeping an eye out on the large route fire burning in los angeles county coming up tonight at 10 30, we'll have a live report from castaic, where hundreds of people are forced to pack up and leave. new attendant 83 year old man loved by his family and community was remembered tonight at a vigil was held right near the west oakland intersection where he was killed by a hit and run driver. ktvu is amberleigh live tonight with the story in oakland, amber mike family members tell me they want justice. they say they cannot fathom how a driver can hit someone and leave the scene. honked in support of a vigil held at the intersection in west oakland, where willie jackson was killed by a hidden run driver. his family says the 83 year old was driving when a woman speeding in a white audi struck jackson saturn for him to go this way. that's not right. the area before police arrived. jackson died at the scene. family members say the driver has not been arrested,

uc berkeley house energy economist severin bornstein, who is also a state power grid, governor, says this well there's some good news and some bad news. uh the good news is the grid in california is better prepared than it was a couple of years ago. in storage batteries alone. there's almost twice the generating capacity of the state's largest power plant , the diablo canyon nuclear plant. this new supply is supercritical on extreme heat days when demand peaks from 4 to 9 pm when solar power fades away when the sun sets ah, i think we will be able to ah, maintain the supply in california more effectively, but extreme heat is often windless heat, which severely reduces california's wind power to make up for that natural gas power plants pick up the huge shortfall, but there are less efficient when it's hot , and sometimes they trip off line plants. trip off at the same time, that can definitely complicate things. so during extreme heat waves, california depends on power imports from other states. this is going to be a west wide heatwave, which makes it harder to buy power from elsewhe
