With nearly 18,000 megawatts of capacity, Texas, if it were a country, would be the sixth-largest generator of wind power in the world, right behind Spain. Now Texas is preparing to add several thousand megawatts moreroughly equal to the wind capacity that can be found in all of California. Most of these turbines are in west Texas, one of the most desolate and windy regions in the continental United States. Fifteen years ago, when the groundwork for this boom was being set, this area had little but cotton and grain farms, oil fields, scrub and dry riverbeds, and small towns that were mostly withering.
Today its a land of spindly white turbines that line the highwaysand the pockets of landowners. At night, when the wind blows strongest and steadiest, if you stand out in one of the fields you can hear the great blades make a ghostly shoop-shoop sound as they turn. Wind power has brought prosperity to towns that were literally drying up less than a generation ago. In the 2011 drought a lot of people around here would have filed for bankruptcy if not for the turbines, said Russ Petty, one of Rolans brothers, who was giving me a driving tour of the property. What its done is helped keep this land in the family.
It has also shown that a big state can get a substantial amount of its power from renewable sources without significant disruptions, given the right policies and the right infrastructure investments. The U.S. Department of Energys 2015 report Wind Vision set a goal of getting 35 percent of all electricity in the country from wind in 2050, up from 4.5 percent today. In Texas, at times, that number has already been exceeded: on several windy days last winter, wind power briefly supplied more than 40 percent of the states electricity. For wind power advocates, Texas is a model for the rest of the country.
But it also reveals what wind power cant achieve. Overall, wind still represents less than 20 percent of the states generation capacitya number that dips into the low single digits on calm, hot summer days. And even with the wind power boom, the states total estimated carbon emissions were the highest in the nation in 2013, the most recent year for which data is availableup 5 percent from the previous year.

(344 posts)One of the biggest things holding back Wind and Solar is that the industry wants to maintain teh centralized generation and distribution system. They need to move to leasing wind and solar installations on every building and charge for maintenance/leasing. That would reduce the need for large centralized installations and make home generation accessible to all.

(19,937 posts)[font size=4]New analysis nearly doubles previous estimates and shows U.S. building rooftops could generate close to 40 percent of national electricity sales[/font]
March 24, 2016
[font size=3]Analysts at the Energy Department's National Renewable Energy Laboratory (NREL) have used detailed light detection and ranging (LiDAR) data for 128 cities nationwide, along with improved data analysis methods and simulation tools, to update its estimate of total U.S. technical potential for rooftop photovoltaic (PV) systems. The analysis reveals a technical potential of 1,118 gigawatts (GW) of capacity and 1,432 terawatt-hours (TWh) of annual energy generation, equivalent to 39 percent of the nation's electricity sales.
This current estimate is significantly greater than that of a previous NREL analysis, which estimated 664 GW of installed capacity and 800 TWh of annual energy generation. Analysts attribute the new findings to increases in module power density, improved estimation of building suitability, higher estimates of the total number of buildings, and improvements in PV performance simulation tools.
The analysis appears in "Rooftop Solar Photovoltaic Technical Potential in the United States: A Detailed Assessment." (PDF) The report quantifies the technical potential for rooftop PV in the United States, which is an estimate of how much energy could be generated if PV systems were installed on all suitable roof areas.
To calculate these estimates, NREL analysts used LiDAR data, Geographic Information System methods, and PV-generation modeling to calculate the suitability of rooftops for hosting PV in 128 cities nationwide-representing approximately 23 percent of U.S. buildings-and provide PV-generation results for 47 of the cities. The analysts then extrapolated these findings to the entire continental United States. The result is more accurate estimates of technical potential at the national, state, and zip code level.

(33,474 posts)...realistic. I can't believe after 50 years of total bullshit where the failed, toxic and useless solar industry describes itself in terms of peak capacity, that someone in this scam as suddenly released a "solar could" statement using units of energy, specifically TWh, as in it "could" produce 800 of these.
That translates into about three exajoules of energy, or about 91,000 watts of average continuous power, or about 3% of US energy demand annually. The solar industry has never, not once, in 50 years of cheering, ever produced one third of that.
To describe the failed, expensive, and useless solar industry in terms of average continuous power is absurd, though, since the solar industry is not and never will be continuous. Every solar plant on this planet is backed up by a redundant power plant, almost always a gas plant.
The solar industry and the fossil fuel industry depend on one another, the former to mask its unreliability and hidden costs, and the latter to serve as lipstick on the pig.
