El mito de las renovables: llegan las facturas de Zapatero


España tendrá que pagar 128 millones tras perder el primer pleito del recorte de las renovables



Golpe al Estado español en el conflicto que mantiene con varios fondos internacionales sobre el recorte a las renovables. El tribunal del Ciadi, corte de arbitraje de inversiones dependiente del Banco Mundial, ha fallado en contra de España y a favor del fondo Eiser Infraestructure, según ha podido saber EXPANSIÓN.

Eiser cuenta con dos plantas fotovoltaicas en España, de 50 MW cada una, en Extremadura y Castilla-La Mancha. Su desembarco en el sector solar en nuestro país, en 2007, coincidió con la aprobación del Real Decreto 661/2007, que regulaba los incentivos a este tipo de proyectos y que disparó las inversiones en huertos solares. Tras el recorte aplicado por el Gobierno, Eiser contrató al bufete Allen & Overy para demandar al Estado español en diciembre de 2013 ante el Ciadi.

La minería del carbón fue subvencionada en 2016 con 25,3 millones de euros. Las energías renovables con más de 5.000 millones

Un solo trabajador del carbón produce la misma cantidad de energía eléctrica que 79 trabajadores solares



In an April 25 New York Times article (“Today’s Energy Jobs Are in Solar, Not Coal“) reporter Nadja Popovich wrote that “Last year, the solar industry employed many more Americans [373,807] than coal [160,119], while wind power topped 100,000 jobs.” Those energy employment figures are based on a Department of Energy report (“U.S. Energy and Employment Report“) released earlier this year that provides the most complete analysis available of employment in the energy economy.

But simply reporting rather enthusiastically (see the NYT headline again) that the solar industry employs lots of Americans, more than twice as many as the number of coal miners and utility workers at electric power plants using coal, is only telling a small part of the story. Here are some important energy facts that help provide a more complete picture about how much energy is being produced in different sectors, how many workers it takes to produce a given amount of electric power, and which sectors receive the most generous taxpayer handouts.

To start, despite a huge workforce of almost 400,000 solar workers (about 20 percent of electric power payrolls in 2016), that sector produced an insignificant share, less than 1 percent, of the electric power generated in the United States last year (EIA data here). And that’s a lot of solar workers: about the same as the combined number of employees working at Exxon Mobil, Chevron, Apple, Johnson & Johnson, Microsoft, Pfizer, Ford Motor Company and Procter & Gamble.

In contrast, it took about the same number of natural gas workers (398,235) last year to produce more than one-third of U.S. electric power, or 37 times more electricity than solar’s minuscule share of 0.90 percent. And with only 160,000 coal workers (less than half the number of workers in either solar or gas), that sector produced nearly one-third (almost as much as gas) of U.S. electricity last year.

The graphic above helps to quantify the significant differences in electric power output per employee for coal, natural gas and solar workers. In 2016, the coal sector generated an average of 7,745 megawatt hours of electric power per worker, more than twice the 3,812 megawatt hours of electricity generated per natural gas worker, and 79 times more electric power per worker than the solar industry, which produced only 98 megawatt hours of electricity per worker. Therefore, to produce the same amount of electric power as just one coal worker would require two natural gas workers and an amazingly-high 79 solar workers.
