Wind farms cause more environmental impact than previously thought

L.M. Miller, D.W. Keith Climate Impacts of Wind Power. Joule 12:2:P2618-P2632 doi.org/10.1016/j.joule.2018.09.009

We find that generating today’s US electricity demand (0.5 TWe) with wind power would warm Continental US surface temperatures by 0.24°C. Warming arises, in part, from turbines redistributing heat by mixing the boundary layer. Modeled diurnal and seasonal temperature differences are roughly consistent with recent observations of warming at wind farms, reflecting a coherent mechanistic understanding for how wind turbines alter climate. The warming effect is: small compared with projections of 21st century warming, approximately equivalent to the reduced warming achieved by decarbonizing global electricity generation, and large compared with the reduced warming achieved by decarbonizing US electricity with wind. For the same generation rate, the climatic impacts from solar photovoltaic systems are about ten times smaller than wind systems. Wind’s overall environmental impacts are surely less than fossil energy. Yet, as the energy system is decarbonized, decisions between wind and solar should be informed by estimates of their climate impacts.

Renewable energies lower income, increase risk of household poverty

Diogo Santos Pereira, António Cardoso Marques, José Alberto Fuinhas. Are renewables affecting income distribution and increasing the risk of household poverty? Energy, Volume 170, 1 March 2019, Pages 791-803 https://doi.org/10.1016/j.energy.2018.12.199

The worldwide electricity mix has become diversified, mainly through the exploitation of endogenous and green resources. However, doubt has been cast on the much-vaunted advantages of renewables due to some of their characteristics, such as availability, security and affordability. In fact, growth in the installed capacity of renewable energy has increased electricity prices, which raises the question of how households have withstood the cost of energy transition. The main aim of this study is to empirically assess and discuss: (i) whether different types of household have suffered dissimilar effects from the promotion of renewables; (ii) the consequences of promoting renewables on household income; and (iii) if the promotion of renewables has reduced the risk of poverty and social exclusion. A panel data of European countries has been analysed using Kao’s residual cointegration test, and an Autoregressive Distributed Lag approach, to assess the relationships. This paper proves that both income and risk of household poverty are directly linked with renewable energies, in both the short- and long-run. The energy transition to renewables has had negative consequences for households. Thus, the disadvantaged households should be helped to meet the increased cost arising from the energy transition.

Learning the hard way 100% renewable energy is unsustainable

“An inconvenient truth is hanging over Georgetown, Texas: Its celebrated shift to renewable energy doesn’t look like a national model these days. Electric rates are up. Critics are blasting the costs. And the city north of Austin is trying to figure out how to mitigate the situation.” click here

Renewable energy raises prices, sparks riots in Chile

“Chile, which is hosting a major U.N. climate conference in December, earned praise from climate activists for recently imposing a carbon dioxide tax on conventional energy sources and switching the Santiago Metro system to renewable power. Now, the people of Chile are rising up and firing a shot across the bow of other nations considering similar energy taxes and expensive renewable energy programs.” click here

Wind energy is an unsustainable energy technology (Money down the drain.)

“Last week the lobbying arm of the wind energy industry made an unsurprising, though somewhat embarrassing, announcement. It wants a longer lifeline with federal subsidies. So much for wind being the low-cost energy source of the future. ” click here

Free money subsidies for renewable energy are unsustainable, ineffective and must come to an end

“After billions of dollars of “gifts” to the renewables industry, and a doubling of the wholesale electricity price, wind and solar power are still so inefficient and uneconomic that investors can’t make a profit without getting more free money.” click here
