Scotland Nearly Hits Renewable Power Independence

By Gary Cutlack on 05 Jun 2017 at 2:00PM

The turbines dotting the hills of Scotland had a cracking month in May, with the modern white totems to consumerism and their solar panel chums generating 95 per cent of the country's home electrical needs.

That's according to environmental group WWF Scotland, which analysed power generation levels for the month. It found that the wind turbines provided 863,495 MWh of power to the grid during May, with peak output on the windiest and sunniest of days providing 99 per cent of the power needed by homes across the country entirely from renewable sources. Including business use, wind alone generated 46 per cent of the month's needs.

Dr Sam Gardner of WWF Scotland said: "On one day in particular, 15 May, output from turbines generated enough electricity to power 190% of homes or 99% of Scotland's total electricity demand. Month after month, renewables play a vital role in cutting carbon emissions and powering the Scottish economy."

Scotland could've run itself entirely through renewables powered by wind on 11 out of the 31 days in May.

Analysis: Meeting Paris pledges would prevent at least 1C of global warming

6 June 2017

President Trump’s decision to withdraw from the Paris Agreement on climate change has raised questions about the effectiveness of the accord, and how that will change without the US.

In his announcement, Trump incorrectly claimed the deal would avoid just 0.2C of warming. In fact, nine separate studies show, on average, that full implementation of current climate pledges would avoid 1C of warming, compared to a business-as-usual world.

Germany, Denmark and Belgium pledge fivefold increase to the world's offshore wind capacity in a decade

Tuesday 6 June 2017 15:10 BST

There were about 13.8 gigawatts of offshore wind globally last year - these three countries are going to add 60 gigwatts more

The governments of Germany, Denmark and Belgium backed a pledge to install 60 gigawatts of new offshore wind power next decade, more than five times the world's existing capacity.

World Coal Production Just Had Its Biggest Drop on Record

13 June 2017, 15:58 GMT+1

It’s the end of an era for coal.

Production of the fossil fuel dropped by a record amount in 2016, according to BP Plc’s annual review of global energy trends. China, the world’s biggest energy consumer, burned the least coal in six years and use dropped in the U.S to a level last seen in the 1970s, the company’s data show.

Quote:
China is betting on new, small-scale nuclear reactor designs that could be used in isolated regions, on ships and even aircraft as part of an ambitious plan to wrest control of the global nuclear market.

Within weeks, state-owned China National Nuclear Corporation (CNNC) is set to launch a small modular reactor (SMR) dubbed the "Nimble Dragon" with a pilot plant on the island province of Hainan, according to company officials.

Unlike new large scale reactors that cost upward of $10 billion per unit and need large safety zones, SMRs create less toxic waste and can be built in a single factory. A little bigger than a bus and able to be transported by truck, SMRs could eventually cost less than a tenth the price of conventional reactors, developers predict.....................................

Researchers Say New Solar Paint Could Produce Energy
Quote:
Australian researchers say they have developed a solar paint that absorbs water vapor and sunlight, generating clean hydrogen energy in a process that offers a potentially limitless source of power.

The paint features a new compound that acts like silica gel, a drying agent used in sachets to absorb moisture and keep food fresh.

France to ban all new oil and gas exploration

France is to stop granting licences for oil and gas exploration as part of a transition towards environmentally-friendly energy being driven by Emmanuel Macron’s government.

Nicolas Hulot, the “ecological transition” minister said a law would be passed in the autumn.

“There will be no new exploration licences for hydrocarbons,” he told BFMTV.

There's a lot of talk surrounding a behavioral phenomenon termed the "rebound effect", in which the consumer of energy will use more energy after adopting energy efficiency (EE) than predicted by engineering calculations. This is because they'll free up expenditures and by in turn they will use that money on energy and elsewhere. If consumers use that freed money for energy, it's called the direct rebound effect. If they use it for non-energy goods, that's called indirect rebound.

But I see this rebound effect as mainly a mathematical construct, with few particular real-life applications.

This paper succinctly summarizes studies around this topic: http://www.sciencedirect.com/science...40988317301949

Quote:
This type of costless efficiency improvement is introduced by many studies to show the “pure” rebound effect caused solely by an efficiency improvement.



As a first step, our study will focus on the costless energy efficiency improvement to investigate the global rebound effect.
It's apparent that people studying this topic have mainly done so assuming "costless" energy efficiency. The discussion around the rebound effect is only applicable for two cases:

1.) If we assume the government applies an EE standard without any induction via energy prices, and pays for/subsidizes that EE measure so that it’s effectively costless for the consumer.
2.) If we assume an environmentally conscious individual and the investment cost in EE is minimal compared to its benefits; but in that case, that person may not alter his behavior to consume more energy because he’s env. conscious. So we’ll probably only observe the indirect rebound effect.

For other cases, where:
1.) The consumer needs to be incentivized to invest in EE, by way of raising energy prices, or
2.) The government applies the EE standard without paying for the EE measure, or
3.) If we assume an env. conscious individual and an investment cost that is higher than the benefits from lower energy bills (which is likely or else many people would have adopted the EE measure anyway),
The rebound effect is ambiguous, because the consumer would experience a negative change in income.

Does what I said hold water? Are there ideas missing that would reverse what I said?

China to build first "forest city" in 2020

9th July 2017

The masterplan for an eco-friendly "forest city" in China has been revealed by Italian architecture firm, Stefano Boeri Architetti.

[...]

Liuzhou Forest City will be self-sufficient in clean energy, utilising geothermal and rooftop solar power. While this may seem impressive enough, an even greater innovation is the widespread use of vegetation covering every building, of all sizes and functions. A total of 40,000 trees (1.3 for every person) and almost a million plants of more than 100 different species will make this a true "forest city".

Holy shiiiiiiit. It finally happened.

Giant iceberg splits from Antarctic

One of the biggest icebergs ever recorded has just broken away from Antarctica.

The giant block is estimated to cover an area of roughly 6,000 sq km; that's about a quarter the size of Wales.

An US satellite observed the berg on Wednesday while passing over a region known as the Larsen C Ice Shelf.

As the article states, it's not abnormal, and in fact, it's rather small compared to the largest ones in the last 50 years.

Quote:
The new Larsen berg is probably in the top 10 biggest ever recorded, but it is no match for some of the true monsters that have been witnessed in the Antarctic.
The largest observed in the satellite era was an object called B-15. It came away from the Ross Ice Shelf in 2000 and measured some 11,000 sq km. Six years later, fragments of this super-berg still persisted and passed by New Zealand.

In 1956, it was reported that a US Navy icebreaker had encountered an object of roughly 32,000 sq km. That is bigger than Belgium. Unfortunately, there were no satellites at the time to follow up and verify the observation.

It has been known also for the Larsen C Ice Shelf itself to spawn bigger bergs. An object measuring some 9,000 sq km came away in 1986. Many of Larsen's progeny can get wound up in a gyre in the Weddell sea or can be despatched north on currents into the Southern Ocean, and even into the South Atlantic.

Third-hottest June puts 2017 on track to make hat-trick of hottest years

Wednesday 19 July 2017

Last month was the third-hottest June on record globally, temperature data suggest, confirming 2017 will almost certainly make a hat-trick of annual climate records, with 2015, 2016 and 2017 being the three hottest years since records began.

The figures also cement estimations that warming is now at levels not seen for 115,000 years, and leave some experts with little hope for limiting warming to 1.5C or even 2C.

2017 is so unexpectedly warm it is freaking out climate scientists

July 19

“Extremely remarkable” 2017 heads toward record for hottest year without an El Niño episode.

Depressing video, but essential viewing.

The under-reporting of China's emissions, the multi-billions in subsidies that continue to flow into fossil fuels, and the meek progress in reducing our dependence on them... it really does look abysmal in terms of our survival prospects.

Saudi Arabia raised energy prices in 2016, but it is looking for more raises in the future. Chatham House in the UK released a paper in 2011 that was cleverly titled, “Burning oil to keep cool”; about 60% of electricity is currently generated using oil.

In this vein, a recent paper explores three alternative electricity pricing options for households in Saudi Arabia. The authors analyze the impact of fuel and electricity price reforms on the power utilities and households. The most interesting piece of insight for me is that the constraint imposed on the Saudi economy by limited domestic natural gas supply is alleviated as a result of raising electricity prices. Of course, the local scarcity of gas could also be mitigated through imports, but this is a political decision that is not addressed in the analysis.

Saudi Aramco also plans to double natural gas production by 2025 compared to 2015, which will have huge implications on the fuel mix and pollutant emissions in the kingdom. More gas in the future will displace domestic oil use. Lower demand for electricity as a result of higher prices could also signal reduced emissions and burning of oil. This, with the planned 9.5 GW of renewable power generation by 2023.
