National labs: Wind energy costs at or heading to all-time lows

Most studies predict the cost of wind energy will continue to fall through at least 2030, said national laboratory staffers in a new report.

The report, "The Past and Future Cost of Wind Energy," released June 6, is a collaboration among workers from the Lawrence Berkeley National Laboratory and the National Renewable Energy Laboratory, with assistance from European researchers. The crux of the report is that while future trends, drivers and constraints are difficult to predict, the cost of wind-generated electricity will probably continue to decrease in the coming decades.

Onshore wind's levelized cost of energy, or LCOE, fell by a factor of more than three between 1980 and 2000, the researchers said. "However, beginning in about 2003 and continuing through the latter half of the past decade, wind power capital costs increased — driven by rising commodity and raw materials prices, increased labor costs, improved manufacturer profitability, and turbine upscaling — thus pushing wind's LCOE upward in spite of continued performance improvements," they said.

TRA SNOW AND SUN - SOLAR TILE MOUNT

TRA SNOW AND SUN - SOLAR TILE MOUNT

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
