IEA Report: Global CO2 Emissions from Electricity Generation to Plateau

The International Energy Agency (IEA) recently released its 2023 Electricity Market Report and it provides an overview of the trends and developments in the global electricity sector in 2022 and the outlook for 2023-2025. It should be noted at this point that historically IEA reports have proven to significantly underestimate the growth of renewables.

The report covers the impacts of the energy crisis triggered by Russia’s invasion of Ukraine in 2022, which led to record-high energy prices and a sharp decline in electricity demand in the European Union. It also examines the role of renewables and nuclear energy in meeting the growing electricity demand and reducing the CO2 emissions of power generation. Finally, it discusses the challenges and opportunities for electricity security in a world where both the demand and supply of electricity are becoming increasingly weather-dependent.

The report finds that world electricity demand remained resilient in 2022 amid the global energy crisis, rising by almost 2% compared with the 2.4% average growth rate seen over the period 2015-2019. However, the soaring prices for energy commodities, including natural gas and coal, sharply escalated power generation costs and contributed to a rapid rise in inflation. Economic slowdowns and high electricity prices stifled electricity demand growth in most regions around the world, especially in the European Union, which recorded a 3.5% decline year-on-year in 2022. The report also notes that China’s zero-Covid policy weighed heavily on its economic activity and electricity demand growth in 2022, while India and the United States saw strong increases in demand due to their robust post-pandemic recovery and extreme weather conditions.

The report projects that global electricity demand will grow at a much faster pace of 3% per year over the 2023-2025 period, driven by the electrification of the transport and heating sectors and the economic development of emerging and developing economies. The total increase in global electricity demand of about 2 500 terawatt-hours (TWh) out to 2025 is more than double Japan’s current annual electricity consumption. More than 70% of the growth in global electricity demand is set to come from China, India and Southeast Asia combined, with China’s share of global electricity consumption rising to one-third by 2025.

Global changes in electricity supply 2021-2025

The report also analyses the trends and outlook for global electricity supply, highlighting the dominant role of renewables and nuclear energy in meeting the additional demand. Together, they are expected to account for more than 90% of the growth in global electricity supply over the next three years, with China leading the expansion of renewable generation and India, Japan and Korea contributing to the growth of nuclear generation. The report also notes that the share of renewables in the global power generation mix is forecast to rise from 29% in 2022 to 35% in 2025, while the shares of coal- and gas-fired generation are set to fall. As a result, global CO2 emissions from electricity generation are expected to plateau to 2025 and its CO2 intensity will further decline in the coming years.

The report concludes by discussing the challenges and opportunities for electricity security in a world where both the demand and supply of electricity are becoming increasingly weather-dependent. It points out that the energy crisis has renewed interest in the role of nuclear power in contributing to energy security and reducing the CO2 intensity of power generation, especially in Europe and the United States. It also stresses that the substantial growth of renewables will need to be accompanied by accelerated investments in grids and flexibility for their successful integration into the power systems. Finally, it warns that the world’s power systems will face more risks from extreme weather events, such as droughts, heatwaves, storms and floods, which can affect both the supply and demand of electricity.

So, given how conservative the IEA has traditionally been when it comes to its predictions of the future growth of renewables, I think their prediction of renewables growth to 35% by 2025 is very positive, seeing as that implies will reach 35% well before then!

CO2 emissions vs income

CO2 vs GNP 1975-2002

I generated this graph on Prof Hans Rosling’s Gapminder.org site.

The data shows, somewhat surprisingly that the increase in carbon emissions in countries like Ireland and the US from 1975 to 2002 are not in any way mirrored by any increases in China or India.

In the recent Bali talks (and the Kyoto talks before that) the US held up the developing countries as major polluters and refused to sign Kyoto (and created all kinds of fuss at Bali) because of the amounts of pollution being emitted by developing countries.

This is obviously delaying tactics for Bush’s friends in the oil business in Texas and Saudi. The US Ambassador to Ireland conceded that China may exceed the US’s total emissions in 2008. Compare the income per capita between the US and China again and even if Chinese total emissions do exceed the US in 2008, they are still far less polluting per capita than the US.

And the Chinese were looking for a stronger agreement at Bali than the US.

The sooner Bush and his oil cronies are out of office, the sooner we can move on with trying to clean up the planet.

Iranian telecoms regulator should hire Irish broadband suppression expertise

However bad things are in Ireland in relation to our broadband speeds – things are even worse in Iran. According to the Guardian, the government there has ordered all ISPs to limit Internet speeds to 128kb. This is in an effort to:

make it more difficult to download foreign music, films and television programmes, which the authorities blame for undermining Islamic culture among the younger generation. It will also impede efforts by political opposition groups to organise by uploading information on to the net.

Iran also has some of the most stringent filters blocking Internet sites into the country – almost as bad as China’s infamous Great Firewall of China.

Having said that, I know several people in Ireland who’d love if they could get speeds of 128kb ‘cos they are stuck with 44kb dialup.

If Iran is really serious about reducing the speeds of access for its citizens, I suggest they hire in the expertise of Ireland’s Minister for Broadband Suppression and Ireland’s Telecom’s Regulator Isolde Goggin who have successfully managed to keep Ireland at the bottom of the international broadband leagues for years now

Could podcasting get content through the Great Firewall of China?

I wrote a couple of pieces last week about Google’s Internet censorship in China and the debate continues this week.

The four largest American companies who are actively helping the Chinese government censor the Internet are Google, Microsoft, Yahoo, and Cisco Systems. These four companies have been invited to a U.S. congressional subcommittee hearing on February 15 on the subject of U.S. Internet firms operating procedures in China.

The ‘fab four’ failed to turn up for a hearing this Wednesday are were roundly berated by Tom Lantos, D.-Calif., one of the caucus leaders:

Companies that have blossomed in this country and make billions, a country that reveres freedom of speech, have chosen to ignore that core value in expanding their reach overseas, and to erect a ‘Great Firewall’ to suit Beijing’s purposes,” he said. “These massively successful high-tech companies, which couldn’t bring themselves to send their representatives to this meeting today, should be ashamed. With all their power and influence, wealth and high visibility, they neglected to commit to the kind of positive action that human rights activists in China take every day. They caved in to Beijing’s demands for the sake of profits, or whatever else they choose to call it.

It is thought they will attend the Feb 15th hearing!

I note see now that the BBC are reporting that MSN is considering changing its censorship policies:

Brad Smith, Microsoft’s senior lawyer, said it would now remove blog entries only if it gets a “legally binding notice” from the government of that nation…. He added that only people in the nation where the entry breaks local laws will be blocked from seeing the controversial comments. In all other nations access to the entry will be unrestricted.

This is a marginal improvement over MSN’s existing policy of deleting accounts of people who wrote about ‘democracy’, ‘freedom’, or ‘demonstration’ but it is still shoring up the ‘great firewall‘ of China.

Interestingly, Reuters is reporting that Bill Gates has come out against censorship today:

The spread of private e-mail means online users could distribute banned news despite government injunctions, he told a news conference.

“You may be able to take a very visible Web site and say that something shouldn’t be there, but if there’s a desire by the population to know something, it’s going to get out,” he said.

However, Gates said Microsoft, the world’s biggest computer software company, had to meet legal requirements of the countries where it does business.

I have spoken to several representatives of search engines recently and they have all told me that search engines are not indexing the audio content of podcasts and don’t have technologies to do so right now.

I wonder, if podcasts are more difficult to index, is there a role for podcasts to get content through the Great Firewall?

Google founder defends censorship

David Kirkpatrick of Fortune met with Sergey Brin (one of the co-founders of Google) at the World Economic Forum at Davos and asked him about Google’s decision to censor the Internet in China (something I posted about the other day).

Sergey’s reasoning for the censorship:

We ultimately made a difficult decision, but we felt that by participating there, and making our services more available, even if not to the 100 percent that we ideally would like, that it will be better for Chinese Web users, because ultimately they would get more information, though not quite all of it.

In the same report, David Kirkpatrick also talks to Human Rights Watch boss Ken Roth – Ken’s attitude to this mirrors the comments I made in my post – Ken said:

the answer is only going to come through safety in numbers. And it’s going to require all of the search engines to get together and say “None of us will do this.” And China needs search engines. If it can pick them off one at a time, it wins. If it faces all of the search engines at once banding together, the search engines win.

Google censors the Internet

The New York Times published an article yesterday (and I think I heard a reference this morning on Morning Ireland) about Google’s new Google.cn site.

According to the article, the new Chinese version of the Google search engine:

will not allow users to create personal links with Google e-mail or blog sites, will comply with Chinese law and censor information deemed inappropriate or illegal by the Chinese authorities

One of the reasons Google is hobbling its own technology in China is that Google.com is losing ground in the search market in China to Baidu.com – a Chinese search engine due to government censorship on some of Google.com’s content. A pre-censored Google.cn should have no such issues.

Google will argue that it is not putting profit before human rights – it is merely complying with the law of the land it wants to make profits in (they might not use that terminology exactly!) – the same as all the other major tech suppliers working in China (Cisco, Yahoo!, MSN, etc.). However, if these companies worked together, they could flout the repressive laws in China and theree would be little the Chinese Government could do against such a united front from their most important IT suppliers.

The price of doing business in China? You have to be prepared to sell your soul.

UPDATE:
I see John Battelle and Danny Sullivan of SearchEngineWatch have pieces on this as well.

Google’s motto of “Do no Evil” should now be changed to “Do no Evil (unless it interferes with the bottom line)”, I guess!
