THE ROAD FROM PARIS: CHINA’S CLIMATE U-TURN

by Presse Release, GWPF,  December 12, 2018


For all its green talk, China is sticking to fossil fuels

London, 12 December – While leaders of western countries fret about their greenhouse gas emissions in Katowice, China is forging ahead with new projects and investments in coal and gas. According to a new paper from the Global Warming Foundation (GWPF), the Communist Party’s survival depends on delivering economic growth and cleaner air.

China: No Wind Or Solar If It Can’t Beat Coal On Price

by  John Parnell, January 10, 2019 in Forbes


China has said it will not approve wind and solar power projects unless they can compete with coal power prices.

Beijing pulled the plug on support for large solar projects, which had been receiving a per kWh payment, in late May. That news came immediately after the country’s largest solar industry event and caught everyone by surprise.

Officials are understood to have been frustrated at seeing Chinese suppliers and engineering firms building solar projects overseas that delivered electricity at prices far below what was available back home.

BP just discovered a billion barrels of oil in the Gulf of Mexico

by Tom DiChristopher, January 8, 2019 in CNBC


KEY POINTS
  • BP discovers 1 billion barrels of oil at its Thunder Horse field in the Gulf of Mexico.
  • The oil giant also says it will spend $1.3 billion to develop a third phase of its Atlantis offshore field south of New Orleans.
  • BP credits its investment in advanced seismic technology for speeding up its ability to confirm the discoveries.

Can wind and solar replace fossil fuels?

by Richard Patton, January 1, 2019 in WUWT


Statements implying that wind and solar can provide 50% of the power to the grid are not difficult to find on the internet. For example, Andrew Cuomo announced that

“The Clean Energy Standard will require 50 percent of New York’s electricity to come from renewable energy sources like wind and solar by 2030…”

Considering that the wind is erratic, and the solar cells only put out full power 6 hours per day, it seems a remarkable statement. Can intermittent energy actually supply that much power?

For some answers, we turn to Germany, which has some of the highest electric bills in the world as well as a high proportion of its electric power produced by wind and solar (19%). Let’s take a look at German consumption and generation.

 

Germany’s green transition has hit a brick wall

by O. Lundseng at al., December 21, 2018 in WUWT


More people are finally beginning to realize that supplying the world with sufficient, stable energy solely from sun and wind power will be impossible.

Germany took on that challenge, to show the world how to build a society based entirely on “green, renewable” energy. It has now hit a brick wall. Despite huge investments in wind, solar and biofuel energy production capacity, Germany has not reduced CO2 emissions over the last ten years. However, during the same period, its electricity prices have risen dramatically, significantly impacting factories, employment and poor families.

Germany has installed solar and wind power to such an extent that it should theoretically be able to satisfy the power requirement on any day that provides sufficient sunshine and wind. However, since sun and wind are often lacking – in Germany even more so than in other countries like Italy or Greece – the country only manages to produce around 27% of its annual electric power needs from these sources.

WHY RENEWABLE ENERGY CANNOT REPLACE FOSSIL FUELS BY 2050

by Robert Lyman, May 2016 in FriendsOfScience


A number of environmental groups in Canada and other countries have recently endorsed the “100% Clean and Renewable Wind, Water and Sunlight (WWS)” vision articulated in reports written by MarkJacobson, Mark Delucci and others. This vision seeks to eliminate the use of all fossil fuels (coal, oil and natural gas) in the world by 2050. Jacobson, Delucci et. al. have published “all-sector energy roadmaps”in which they purport to show how each of 139 countries could attain the WWS goal. The purpose of this paper is to examine whether the 100% goal is feasible.

While a range of renewable energy technologies (e.g. geothermal, hydroelectric, tidal, and wave energy) could play a role in the global transformation, the world foreseen in the WWS vision would be dominated by wind and solar energy. Of 53,535 gigawatts (GW) of new electrical energy generation sources to be built, onshore and offshore wind turbines would supply 19,000 GW (35.4%), solar photovoltaic (PV) plants would supply 17,100 GW (32%) and Concentrated Solar Power plants (CSP) would supply 14,700 GW (27.5%). This would cost $100 trillion, or $3,571 for every household on the planet.

Climate Scientists Reject Wind And Solar, Demand Nuclear-Powered Future

by Stop These Things, November 20, 2108 in ClimateChangeDispatch


In the climate alarmists’ worldwide crusade against carbon dioxide gas, only the most delusional still believe that wind and solar power add anything to their arsenal.

As we have said repeatedly, nuclear power is the only stand-alone power generation source which is capable of delivering power on demand, without CO2 emissions being generated in the process.

Perversely, notwithstanding that Australia is in the top three uranium exporters, it’s the only G20 country with a legislated prohibition on nuclear power generation…

Why China Indirectly Controls EV Markets

by Haley Zaremba, November 4, 2018 in OilPrice


China produces about two thirds of the whole world’s supply of lithium ion batteries, the most common battery type used in electric vehicles. Furthermore, these highly valuable batteries make up a staggering 40 percent of the cars’ value. As it stands, Europe is far from being able to compete with China when it comes to the production of lithium ion batteries. In fact, currently the entire continent is estimated to hold just 1 percent of the market.

Paradigm Shift? The ‘Belief’ That Bioenergy Is Climate-Friendly Is Now Recognized As A ‘Major Error’

by K. Richard, November 1, 2018 in NoTricksZone/PNAS


Governments vociferously promote bioenergy as renewable, sustainable, and carbon-neutral. But scientists are increasingly characterizing this “belief” as a “major error”, as bioenergy generates more CO2 emissions per kWh than burning coal does, and the projected rapid growth in bioenergy will serve to ‘increase atmospheric CO2 for at least a century’ as well as clear forests and destroy natural ecosystems.

Les limites des lois de la physique dans la transition énergétique

by Alain Préat, 17 octobre 2018, in ScienceClimatEnergie


Bertrand Cassoret a récemment publié un excellent ouvrage [1] sur le sujet. Cet auteur est ingénieur et docteur en génie électrique et s’est lancé sans a priori dans le dédale des ‘promesses’ des énergies vertes en tentant de préciser ce qu’il en est à partir d’une quantification rigoureuse des rendements énergétiques réels. Pourquoi ‘réels’ ? Simplement parce qu’il faut débusquer tout ce qui n’est pas mis en avant (principalement pertes énergétiques cachées) et surtout mettre à plat les ordres de grandeurs du monde de l’énergie. Sa conclusion sera sans appel « même si l’efficacité énergétique est utile et même indispensable, elle ne sera pas suffisante… il est nécessaire de modifier l’usage que l’on fait des appareils consommateurs ». Autre conclusion sans appel « mon objectif n’est pas de critiquer les énergies renouvelables, ni les nécessaires mesures d’efficacité, mais plutôt de montrer qu’elles pèsent bien peu face à l’ampleur des problèmes ».

Wide-scale US wind power could cause significant warming

by James Temple, October 4, 2018 in MITTechnologyReview


Wind power is booming in the United States.

It’s expanded 35-fold since 2000 and now provides 8% of the nation’s electricity. The US Department of Energy expects wind turbine capacity to more than quadruple again by 2050.

But a new study by a pair of Harvard researchers finds that a high amount of wind power could mean more climate warming, at least regionally and in the immediate decades ahead. The paper raises serious questions about just how much the United States or other nations should look to wind power to clean up electricity systems.

Highlights

  • Wind power reduces emissions while causing climatic impacts such as warmer temperatures
  • Warming effect strongest at night when temperatures increase with height
  • Nighttime warming effect observed at 28 operational US wind farms
  • Wind’s warming can exceed avoided warming from reduced emissions for a century

Germany’s Energiewende program exposed as a catastrophic failure

by Larry Hamlin, September 30, 2018 in WUWT


“Germany’s Federal Audit Office has accused the federal government of having largely failed to manage the transformation of Germany’s energy systems.”

“A little more than a year before Germany’s climate-policy “milestone 2020”, the auditing body has concluded a catastrophic assessment of the government’s energy policy. Germany would miss its targets for both reducing greenhouse gas emissions and primary energy consumption as well as for increasing energy productivity and the share of renewable energy in transport. At the same time, policy makers had burdened the nation with enormous costs.”

The audit further concluded that the program is a monumental bureaucratic nightmare where “The Federal Government, incidentally, does not have an overall grasp of the costs or any transparency in this respect.”

France to cut renewable growth

by The Energy Advocate, September 26, 2018


The French Government will drastically reduce the growth of its renewable spending in 2019, with the ecology ministry’s draft budget showing a 1.3% rise, which will effectively be flat after inflation.

Total spending on renewable projects will equate to €7.3 billion and will mostly go towards wind and solar schemes.

The move will force France to seek alternative forms of energy after last year France had to import UK coal power to fuel the country as temperatures plummeted in the winter months.

“There Has Never Been An Energy Transition”

by David Middleton, September 20, 2018T in WUWT


One of my favorite sayings is, “We didn’t leave the Stone Age because we ran out of stones.”  Technically we never left the Stone Age because we use more rocks now than we did in the Stone Age.

And we never left the “Wood Age.”  There was no energy transition from biomass (wood) to fossil fuels. Coal piled on top of biomass, oil piled on top of coal and natural gas piled on top of oil

Renouvelables : le déclin des investissements

by Rémy Prud’homme, 16 septembre 2018, in Contrepoints


Michael Bloomberg est un milliardaire américain (pas un petit : l’une des vingt plus grosses fortunes mondiales), membre du parti démocrate, ancien maire de New York. C’est naturellement un farouche défenseur de l’environnement, ce qui lui a valu d’être nommé par le Secrétaire Général des Nations-Unies « envoyé spécial pour l’action climatique ». On ne peut pas le soupçonner de minorer le développement des énergies propres.

LES INVESTISSEMENTS DANS L’ÉNERGIE « PROPRE » SONT EN DÉCLIN

Le rapport1 que publie l’entreprise qu’il dirige (en fait une filiale consacrée aux énergies nouvelles) montre que les investissements dans « l’énergie propre », définie comme l’éolien et le photovoltaïque, ont diminué dans la plupart des pays du globe au cours des années 2010. Le point haut a été atteint en 2011. Depuis cette date, les investissements stagnent ou diminuent, à des taux divers selon les pays et les années.

La COP21, en 2015, devait sauver le monde grâce à des investissements massifs dans ces domaines. Elle n’a rien fait de tel. Au contraire, les années 2016, 2017 et 2018 sont marquées par une accélération de la baisse des investissements.
