Global Energy & CO2 Status Report

by IEA, March 2019 (.pdf)


Key Findings 2018

Global energy consumption in 2018 increased at nearly twice the average rate of growth since 2010, driven by a robust global economy and higher heating and cooling needs in some parts of the world. Demand for all fuels increased, led by natural gas, even as solar and wind posted double-digit growth. Higher electricity demand was responsible for over half of the growth in energy needs. Energy efficiency saw lacklustre improvement.

Energy-related CO2 emissions rose 1.7% to a historic high of 33.1 Gt CO2. While emissions from all fossil fuels increased, the power sector accounted for nearly two-thirds of emissions growth. Coal use in power alone surpassed 10 Gt CO2, mostly in Asia. China, India, and the United States accounted for 85% of the net increase in emissions, while emissions declined for Germany, Japan, Mexico, France and the United Kingdom.

Oil demand rose by 1.3% in 2018, led by strong growth in the United States. The start-up of large petrochemical projects drove product demand, which partially offset a slowdown in growth in gasoline demand. The United States and China showed the largest overall growth, while demand fell in Japan and Korea and was stagnant in Europe.

Natural gas consumption grew by an estimated 4.6%, its largest increase since 2010 when gas demand bounced back from the global financial crisis. This second consecutive year of strong growth, following a 3% rise in 2017, was driven by growing energy demand and substitution from coal. The switch from coal to gas accounted for over one-fifth of the rise in gas demand. The United States led the growth followed by China.

Coal demand grew for a second year, but its role in the global mix continued to decline. Last year’s 0.7% increase was significantly slower than the 4.5% annual growth rate seen in the period 2000- 10. But while the share of coal in primary energy demand and in electricity generation slowly continues to decrease, it still remains the largest source of electricity and the second-largest source of primary energy.

La transition électrique européenne, une impasse?

by J.P. Schaeken Willemaers, 29 mars 2019 in ScienceClimatEnergie


La transition énergétique est abondamment traitée dans les médias, souvent de manière univoque (ce que d’aucuns appellent le débat confisqué) en ignorant les conséquences socio-économiques. Dans ce papier, nous nous limiterons à sa composante électrique.
Rappelons tout d’abord que la finalité première d’un système électrique est d’assurer l’adéquation entre la production et la consommation d’électricité.


Il va de soi, quoique ce ne soit pas évident pour tout le monde, qu’il faut anticiper les adaptations nécessaires du système avant de procéder à la mise en œuvre du changement. Dans ce processus, l’analyse de l’impact sur la transmission et la distribution d’électricité et sur la continuité des services ainsi que la réalisation des travaux correspondants requis, sont prioritaires. Or aucun gouvernement ayant décidé de réduire drastiquement les émissions de gaz à effet de serre (GES), ne s’est soucié des conséquences de leurs décisions. Ceci explique les déboires des pays qui se sont précipités dans une stratégie de pénétration accélérée de production d’électricité renouvelable intermittente.

Report : The “New Energy Economy”: An Exercise in Magical Thinking

by Mark P. Mills, March 26, 2019 in ManhattanInstitute


EXECUTIVE SUMMARY

A movement has been growing for decades to replace hydrocarbons, which collectively supply 84% of the world’s energy. It began with the fear that we were running out of oil. That fear has since migrated to the belief that, because of climate change and other environmental concerns, society can no longer tolerate burning oil, natural gas, and coal—all of which have turned out to be abundant.

So far, wind, solar, and batteries—the favored alternatives to hydrocarbons—provide about 2% of the world’s energy and 3% of America’s. Nonetheless, a bold new claim has gained popularity: that we’re on the cusp of a tech-driven energy revolution that not only can, but inevitably will, rapidly replace all hydrocarbons.

This “new energy economy” rests on the belief—a centerpiece of the Green New Deal and other similar proposals both here and in Europe—that the technologies of wind and solar power and battery storage are undergoing the kind of disruption experienced in computing and communications, dramatically lowering costs and increasing efficiency. But this core analogy glosses over profound differences, grounded in physics, between systems that produce energy and those that produce information.

In the world of people, cars, planes, and factories, increases in consumption, speed, or carrying capacity cause hardware to expand, not shrink. The energy needed to move a ton of people, heat a ton of steel or silicon, or grow a ton of food is determined by properties of nature whose boundaries are set by laws of gravity, inertia, friction, mass, and thermodynamics—not clever software.

This paper highlights the physics of energy to illustrate why there is no possibility that the world is undergoing—or can undergo—a near-term transition to a “new energy economy.”

Among the reasons:

Global CO2 Emissions Rose By 1.7% Last Year, As Energy Demand Climbs

by P. Homewood, March 26, 2019 in NotaLotofPeopleKnowThat


Energy demand worldwide grew by 2.3% last year, its fastest pace this decade, an exceptional performance driven by a robust global economy and stronger heating and cooling needs in some regions. Natural gas emerged as the fuel of choice, posting the biggest gains and accounting for 45% of the rise in energy consumption. Gas demand growth was especially strong in the United States and China.

Demand for all fuels increased, with fossil fuels meeting nearly 70% of the growth for the second year running. Solar and wind generation grew at double-digit pace, with solar alone increasing by 31%. Still, that was not fast enough to meet higher electricity demand around the world that also drove up coal use.

As a result, global energy-related CO2 emissions rose by 1.7% to 33 Gigatonnes (Gt) in 2018. Coal use in power generation alone surpassed 10 Gt, accounting for a third of the total increase. Most of that came from a young fleet of coal power plants in developing Asia. The majority of coal-fired generation capacity today is found in Asia, with 12-year-old plants on average, decades short of average lifetimes of around 50 years.

 

REPORT: GREEN ENERGY ECONOMY IS SIMPLY ‘IMPOSSIBLE’

by Mark P. Mills, March 23, 2019 in GWPF


Hydrocarbons—oil, natural gas, and coal—are the world’s principal energy resource today and will continue to be so in the foreseeable future. Wind turbines, solar arrays, and batteries, meanwhile, constitute a small source of energy, and physics dictates that they will remain so. Meanwhile, there is simply no possibility that the world is undergoing—or can undergo—a near-term transition to a “new energy economy.”

The Green New Deal’s Weak Chain Of Logic

by Daniel G. Jones, March 18, 2019 in ClimateChangeDispatch


Reagan observed: “It isn’t so much that liberals are ignorant. It’s just that they know so many things that aren’t so.”

So it is with the Green New Deal. Most liberals regard it as a simple proposition: Global warming is a really big problem, and it’s our fault, so let’s fix it.

But closer analysis reveals that the argument for the Green New Deal rests upon a long chain of interdependent assertions, every one of which must be believed for the problem to be of sufficient peril to warrant their drastic solution.

Here are links in their chain of logic. If you doubt the truth of any single step, you must discard the entire argument.

Unreliable Power Source…Adding Capacity Does Little To Solve Germany’s Green Energy Power Gaps

by P. Gosselin, March 6, 2019 in NoTricksZone


German wind park protest group MenschNatur posted here explaining how even adding more wind and solar capacity does not make Germany’s energy supply any more reliable, but in fact may even make it less so.

Time and again the proponents of the Energiewende (transition to green energies) promote the idea that we must invest massively in more wind and solar power plants and that only an accelerated expansion can save the transformation to green energies.

Thus the wind energy protest group MenschNatur has taken a closer look at the increase in installed nominal capacity over the past years and compared it to what actually gets fed into the grid.

How increases in wind generator capacity affects the feed-in power is described in the following diagram. MenschNatur plotted the installed capacity of all German onshore wind turbines from 2014 to 2018, along with what actually got fed in.

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.
