Clean, renewable wind and solar power may be the most-preferred fossil fuel alternatives, but their land-hungry collecting requirements make them difficult options for replacing more conventional power sources, according to a British energy expert.David MacKay, chief scientific adviser to the United Kingdom’s Department of Energy and Climate Change and a professor of natural philosophy in the Department of Physics at Cambridge University, crunched the numbers on how much energy some sources can generate per unit area to illustrate that renewable types probably will be part of a future energy mix, rather than the solutions.MacKay, author of the recent book, “Sustainable Energy — Without the Hot Air,” said that to generate enough power to replace fossil fuels, some renewable sources would have to cover enormous swaths of territory. Wind farms, for example, would have to cover half of Britain to meet that nation’s energy needs, he said. MacKay said he has been accused of being anti-wind for pointing this out. He’s actually pro-wind, he said, but quipped that he’s even more “pro-arithmetic.”“The message about renewables is that, to make a difference, renewable facilities have to be country-sized,” MacKay said, noting that some people are already fighting construction of wind farms in areas they deem inappropriate.MacKay spoke Friday (April 2) at the Northwest Laboratories as part of the Future of Energy lecture series sponsored by the Harvard University Center for the Environment (HUCE). MacKay was introduced by HUCE director Daniel Schrag, Sturgis Hooper Professor of Geology and professor of environmental science and engineering.Though MacKay said moving to an all-renewable power system would be difficult, he also said the status quo cannot continue. Fossil fuels are not only warming the globe, they are a finite resource. In addition, he said, the need to import fossil fuels creates security and supply concerns. As much as 90 percent of future energy should come from non-fossil fuel sources, he said.“We have an addiction to fossil fuels, and it’s not sustainable,” MacKay said.MacKay broke down current energy demands into simple units and then took a cut-and-paste approach with alternatives, saying he’s not particularly fussy about the exact combination that replaces fossil fuels, as long as it gets done.The generating capacity per unit area of nuclear power plants is 400 times that of wind farms, making them a potentially useful part of a future mix. Besides wind and solar power, also in the mix could be clean coal plants and hydropower from unconventional sources, such as tides and ocean currents. MacKay also advocated decreasing demand by insulating buildings better, by switching to more efficient building systems such as heat pumps, by turning down thermostats, and by turning off appliances when not in use. Transportation, he said, should be predominantly electric-powered, and solar power generation would be more efficient if plants were built in regions that get lots of sun, such as the Sahara Desert and the American Southwest.“Getting off fossil fuels will not be easy, but it is possible,” MacKay said.

Though the fall semester is just a mirage on the distant horizon for most students, a few are already looking ahead to November and the California elections.“I don’t think people realize that November is not that far away. It’s really just around the corner from a campaign standpoint,” said Alexa Ekman, president of USC College Republicans.Two important California contests will be decided this November — the race for Gov. Arnold Schwarzenegger’s office and Sen. Barbara Boxer’s bid for re-election.Students at USC have recently begun throwing their support behind their favorite candidates. Two Silicon executives — both women — have already drawn organized student support.Daniel Gabel, Los Angeles regional chair for Students for Meg Whitman, founded and co-chairs a chapter of the group at USC. The group supports the former eBay CEO, who is one of several Republican candidates for governor.Ekman and Lauren Korbatov are co-chairing Carly Fiorina’s campus campaign group, USC Students for Carly, which started a few weeks ago. Fiorina, a former Hewlett-Packard CEO, is running against Boxer.Ekman said many students don’t know who the candidates are at this point, and she thinks it is because the elections seem so far away.She said she expects student involvement to heat up in April and May, but that it likely won’t reach the levels seen during the 2008 presidential election.“For the presidential campaign, every student was wearing a pin, was volunteering,” Ekman said. “It was exciting to be involved, to take a position. Once this cycles back around again, there will be a resurgence in student activity but probably not to the same extent.”Many students said they don’t know who the candidates are or where they stand on key issues.Geovanni Juarez, a junior majoring in public relations, said he hasn’t been paying attention to the campaigns.“I haven’t looked into it yet, I’m kind of in the dark,” Juarez said. “I’ve been busy with the start of the semester. As the election approaches I’ll obviously take a side.”Stacy Jones, a freshman majoring in chemical engineering, said she hasn’t followed politics to this point, but she plans to start learning about the races soon.“I don’t keep up with politics because I’ve never been able to vote,” she said. “I didn’t want to get involved and then get upset if I didn’t have the power to change things. Now that I can vote this year, I certainly plan to get involved.”Dan Schnur, director of the Jesse M. Unruh Institute of Politics, said it’s too early to know whether the unprecedented student involvement in the 2008 campaign was the beginning of a general trend in student activism or an aberration. As a California state election, it is likely it won’t have such a marked manifestation on campus, since many students are registered to vote in their home states.But Schnur emphasized that student activism is especially valuable to politicians during these elections.“The vote from a 19- or 20-year-old counts just as much as the vote of a 50- or 60-year-old,” Schnur said. “And young people are much more likely to donate time volunteering. Finally, there’s great symbolic value in having the support of the next generation; it sends a message to all voters. So there’s statistical value, organizational value and a symbolic value for having students involved in a campaign.”Both Students for Meg Whitman and USC Students for Carly are currently focusing on recruiting members and raising awareness about the groups’ respective candidates.Gabel said Students for Meg Whitman has recruited about 30 members in the last few weeks and the group hopes to increase that number substantially this month. They will have a table on Trousdale Parkway next week.“This month is all about recruiting, raising awareness about Meg’s campaign, finding people who are interested in becoming involved,” Gabel said. “[In] March [we] will shift to spreading her message and her platform, organizing events on campus, bringing in local politicians who support her, allowing students to become involved in the nitty gritty of the campaign, walking precincts, calling voters, etc.”Students for Carly will also be hosting speakers, and Fiorina herself has already visited campus to speak with students. Ekman said the group is also planning to host forums.“It’s a way for us to find out what [students] want or expect,” Ekman said. “We have to go out and educate young voters about why [Fiorina] is the best candidate for the United States Senate. Education of potential members and voters is going to be our main focus.”So far, only Republican candidates have generated student groups on campus, but Schnur said it’s only a matter of time before groups will form in support of the Democratic candidates — specifically for Boxer and former California Governor Jerry Brown.“Neither Boxer nor Brown has a primary challenge, so they’re able to start their campaigns a little more gradually,” Schnur said. “My guess is by fall you’ll see very sizable student groups for both parties’ nominees.”
Wearing his number 34 jersey, former Dodgers pitcher Fernando Valenzuela threw out the ceremonial first pitch to Dodgers catcher Tim Federowicz. Mike Brito, the scout who discovered Valenzuela in Mexico as a teenager in 1978, recreated his famous radar gun-holding pose behind Federowicz with an actual radar gun. Tommy Lasorda did the honors of announcing “It’s time for Dodgers baseball” prior to the game.Dodgers special advisor Sandy Koufax and former manager Joe Torre were also in attendance. Former Dodger Casey Blake was at the game, too.Jessica Sanchez, an American Idol product, sang the National AnthemEthier updateFor the first time this series, Andre Ethier (ankle) took fly balls in center field as the Dodgers took batting practice. Ethier has been limited to pinch-hitting duties this series and only began running the bases Thursday.Ethier took advantage of the off-day in the schedule Saturday and appeared to be running as normally as he has in weeks. The outfielder said Friday in Atlanta that he would “figure out some more ways to maybe get comfortable and running on this full time.” Anyone for $1,000?The Dodgers had a silent auction Sunday, and a Puig jersey had the highest asking price. Of course. A Puig jersey — one of the top-five best sellers in Major League Baseball — had a starting bid of $1,000 and was up to $2,000 an hour before the game. A Clayton Kershaw jersey had a starting bid of $400. All of the proceeds went to the Dodgers Foundation.Staff writer Jill Painter contributed to this report Capuano started in 20 of his 24 appearances this season, none after Sept. 6. He suffered a strained groin in that game and was forced to leave in the second inning, an injury that caused him to miss the next three weeks.Not until the final weekend of the regular season did Capuano return. He pitched one scoreless inning of relief in two of the Dodgers’ three games against the Colorado Rockies. That, and a wealth of experience, was enough to earn him a postseason roster spot over right-handers Brandon League, Edinson Volquez and Carlos Marmol.Ryu lasted just three innings, allowing four runs. The Dodgers led 6-4 when he left the game and were ahead 10-4 when Howell relieved Capuano in the seventh.Celebrity sightingsAmong the celebrities in attendance for Game 3 were musician Jack White, comedian Conan O’Brien, producer Rob Reiner and actor Eric Stonestreet. Newsroom GuidelinesNews TipsContact UsReport an Error Chris Capuano did more than just stop the bleeding after a shaky start by Hyun-Jin Ryu on Sunday.The veteran left-hander validated the Dodgers’ decision to include him on their 25-man National League Division Series roster.Pitching the first playoff game in a nine-year career that included stops with the Arizona Diamondbacks, Milwaukee Brewers and New York Mets, Capuano tossed three scoreless innings to earn the victory.After replacing Ryu to start the fourth inning, Capuano walked the first batter he faced in the fourth, fifth and sixth, but none of the runners advanced past second base. He struck out three and got a double-play ground ball off the bat of Elliot Johnson in the sixth inning, before giving way to J.P. Howell in the seventh.
