Top Utilities Grow Solar Power Despite Recession
The new SEPA report demonstrates that the utility segment is making a major investment to increase the amount of solar energy in power portfolios, with many utilities doubling the amount of solar power in their portfolio in just one year. The installed solar capacity of the top ten ranked utilities rose 25 percent in a tough economy, from 711 megawatts to 882 megawatts.

Although the sunny West Coast dominates this year’s list, other states are coming on strong including Florida, North Carolina, and Florida. Yes, the availability of sunlight is one driver in the expanded use of solar. Other drivers include the retail price of electricity, state government initiatives such as RPS, and cap-and-trade of emission credits.
There are two primary solar technologies, photovoltaic and concentrating solar power. Photovoltaic (PV) technologies utilize a photosensitive material to generate electricity direct from sunlight. PV can also be magnified using mirrors or lenses in low- or high-concentrations known as concentrating photovoltaic technology or CPV. Concentrating solar power (CSP) technologies utilize mirrors or lenses to concentrate sunlight on a point or line and generate high-temperature heat, which is captured to generate electricity in a later process.
Julia Hamm, Executive Director of SEPA, sees strong growth in both PV and CSP. For example, Southern California Edison is planning a massive 1.3GW of CSP with BrightSource. Arizona Power is planning 125MW of PV. Medium- and utility-scale photovoltaic and concentrating solar thermal power projects are adding around 20 billion of dollars worth of investment.
Some European nations that aggressively use wind power, such as Spain and Denmark, have demonstrated that intermittency is quite manageable when renewable energy is less than 20% of the mix. CSP can take the mix much higher by storing energy in liquids like molten salt for delivery when demand peaks.
#5 on the list, Public Service of Colorado (Xcel Energy), is already experimenting with vehicle-to-grid (V2G Report), which will allow the growing population of electric vehicles to provide power to the grid during peak hours. Utilities are experimenting with several forms of large scale grid-storage which will be promising if significant costs are achieved.
Some 30 years ago, solar was dismissed as impractical. Now that PV manufacturing cost is 100 times less than in early days, utilities are taking the lead in the growing demand for solar power.
John Addison writes about clean transportation and renewable energy. He is the author of the new book - Save Gas, Save the Planet – which includes details of the growing use of renewable energy in powering cars, public transportation, and high-speed rail.
-->United States Wind and Solar Grow as Coal Use Decreases
According to the latest figures published by the U.S. Energy Information Administration (EIA) in its “Electric Power Monthly” report released on March 24, 2009, non-hydro renewable sources of electricity enjoyed double-digit growth during the past year while coal, natural gas, and petroleum experienced notable declines and nuclear power remained stagnant.
Solar, Wind and Biofuels Grew 53 Percent in 2008
Three major clean-energy sectors — solar photovoltaics (PV), wind power, and biofuels — grew 53 percent from $75.8 billion in 2007 to $115.9 billion in revenues in 2008, according to the Clean Energy Trends 2009 report. By 2018, Clean Edge forecasts that these three sectors will have revenues of $325.1 billion.
Wind Hydrogen for less than $3/kilogram
Hydrogen can be produced at a wind turbine site for $5.55 / kg in the near term to $2.27 / kg in the long term, explains ‘Wind Energy & Production of Hydrogen & Electricity - Opportunities for Renewable Hydrogen’ prepared the DOE’s National Renewable Energy Laboratory. A second analysis examined if wind could produce hydrogen [...]
Solar Powers more Vehicles as Gasoline use Drops
Solar is powering more vehicles. American’s have reduced their use of petroleum 5 percent this year. So far, petroleum reduction is the result of fewer miles traveled solo as people cut travel to deal with high gas prices and a slowing economy. At the Solar Power International conference, one notable area of growth is solar covered parking structures with vehicle charging – a cool solution for a planet that is getting hotter.
Real Security after 9/11
On September 11, 2001, thanks to heroes like Avel Villanueva the hundreds of people working for Sun Microsystems in Two World Trade Center all quickly evacuated the building and survived. When Avel saw the damage and fire at One World Trade Center, he paged everyone at Sun to leave Two World Trade Center as quickly, “Please, with calmness, go to the nearest exit. This is not a drill. Get out.”
Los Angeles Metro Installs Solar on Facilities Rooftops
The Metro Board of Directors has approved $5 million for a new solar generation. This starts a comprehensive three-year plan to install solar panels on every Metro Bus and Rail facility within its Los Angeles County service area. Solar panels will be installed on Metro Bus Division 18’s maintenance building rooftop and as shading structures in the employee parking lot and will consist of about 1,600 solar panels that together will generate 417 kilowatts of electricity, enough power to save Metro about $25,000 per month, or $300,000 per year.
General Motors Looks Beyond Oil
“One of the most serious business issues currently facing General Motors is our product’s near total dependence on petroleum as a source of energy. To address this issue, we have been implementing a strategy to displace petroleum through energy diversity and efficiency,” explained Dr. Larry Burns, Vice-President of Research and Development for General Motors, during his keynote speech.
FedEx’s Absolutely, Positively, Cleaner Fleet
With oil topping $100 per barrel, FedEx is also investing in hybrid, alt-fuel, and electric vehicles. FedEx hybrids have accumulated more than 1,000,000 miles in revenue service.100 diesel hybrids are in service globally, primarily in the U.S; 75 more hybrids will be added in 2008. The hybrids are an excellent investment with a 42% improvement in fuel economy.
Solar Power 2007
Solar Power 2007 was such a hot event that registration had to be closed a week prior to the conference opening in Long Beach, California. There was enthusiasm for high growth and technology advancements in photovoltaics (PV) and in large-scale concentrating solar power (CSP). In 2006, PV grew over 40% to $20 billion in revenue and over 2,500 MW of new solar power.
