Climate Change, Global Warming, Pollution, Environmental Degradation and Renewable Energy


Introduction                                                                                                                                            You should watch Al Gore’s ‘An Inconvenient Truth’ for the background to Climate Change. If you are too mean to buy it you can watch extracts on Youtube or borrow my copy. Or you can watch him on TED:

Climate Change and Global Warming - key points and an update
good article:
Fossil Fuels:
http://en.wikipedia.org/wiki/Fossil_fuel 
extract: The Energy Information Administration estimates that in 2007 the primary sources of energy consisted of petroleum 36.0%, coal 27.4%, natural gas 23.0%, amounting to an 86.4% share for fossil fuels in primary energy consumption in the world. Non-fossil sources in 2006 included hydroelectric 6.3%, nuclear 8.5%, and others (geothermal, solar, tidal, wind, wood, waste) amounting to 0.9%. World energy consumption was growing at about 2.3% per year.

Renewable (sustainable) energy (resources)
Renewable energy comes from natural resources such as sunlight, wind, rain, tides, and geothermal heat, which are renewable (naturally replenished). As of 2010, about 16.2% of global final energy consumption comes from renewables, with 10% coming from traditional biomass (e.g. wood), which is mainly used for heating, and 3.4% from hydroelectricity. New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for only 2.8% but have been growing very rapidly. The share of renewables in electricity generation is around 19% (with 16% of global electricity coming from hydroelectricity but only 3% from new renewables).

According to D. G. Victor and K. Yanosek in ‘The Crisis in Clean Energy’, Foreign Affairs July/August 2011 :
after years of very rapid growth (25% a year) the clean energy industry is facing crisis. With the economic crisis public subsidies are no longer sustainable politically. At a global level in 2011 the number of new start-up projects for wind turbines fell for the first time (by 50% in the US). Solar energy and ethanol in the US depend on federal and state subsidies. Private investment in clean energy has fallen. In the EU there have been cut-backs in clean energy subsidies and investment. Germany cut solar energy subsidies in 2010, Italy has capped subsidies and Spain and the Czech Republic are making cuts. China, now the biggest carbon emitter, is maintaining support for the industry but needs to improve the electrical power grid to link installations (e.g. wind farms) to consumers. On the stock markets share values for clean energy companies are falling. So far investment in off-shore wind farms in Northern Europe has continued and roof-top solar energy technology in the US remains popular in California and Florida and New Jersey. However, the general outlook is gloomy. Nuclear power, contested by some as not truly clean, feared by many among the public as dangerous, but supported by others as cheap and reliable, is unlikely to receive significant investment in the near future after the events following the tsunami in Japan.
      So Western countries, in particular, face a tough choice – trying to invest to prevent global warming and ensure future energy security while faced with the ongoing economic crisis, rising public debt and, for most, a trade deficit. So far there has been investment in, and purchase of, established clean energy technologies rather than investment in innovative future technologies that could be much more competitive with traditional fossil fuel energy sources. Solutions are necessary that do not depend on government subsidies that the US and the EU may no longer be able to afford. Scarce public funds should therefore go to innovation and to supporting research and promising projects (e.g. organisms that can create bio-fuels) and commercial-scale testing of such new technologies. Most existing technologies are not economically viable without subsidies, so the current crisis should be seen as an opportunity to reconsider strategy in favour of innovation and commercialization to lower costs and achieve competitiveness. This could be fostered by cross-border partnerships to engage in emerging markets, e.g. between EU companies and China.

The EU Emissions Trading System
https://www.foeeurope.org/carbon-trading
An critical article on the EU Emissions Trading System: failing to deliver
http://www.foeeurope.org/sites/default/files/publications/FoEE_ETS_failing_to_deliver_1010.pdf
What Friends of the Earth Europe calls for:


A short extract:

End the reliance on the EU-ETS. Priority should be given to other policy options, such as regulation, taxation and subsidies which are able to deliver the scale and speed of emissions reductions that are necessary to avoid catastrophic climate change.
The most dangerous loopholes in the EU-ETS must be removed by ending overseas offsets, stopping free permits to polluters, introducing a much tighter cap, and preventing the use of banked permits from earlier phases of the EU-ETS scheme. Auctioning money must not be used to subsidize fossil fuels, such as state aid for new coal power plants, or false solutions such as nuclear power or CCS.
The EU-ETS must not be expanded by either linking with schemes outside of the EU or instituting sectoral trading with developing countries. Carbon markets cannot be a replacement for mandatory targets under a binding international climate agreement, and adequate and appropriate public funding for climate finance in developing countries.
The EU-ETS should not be used as an argument to prevent other policies such as setting binding energy efficiency targets or to prevent any other measures at national level such as national climate laws to tackle industry or industry sector emissions.  

Launched in 2005, the European Union’s Emissions Trading System (EU-ETS) is the largest
carbon trading market in the world. It is the EU’s principal policy mechanism for reducing greenhouse gas emissions in the power generation and industrial sectors. But the EU-ETS is
not delivering the CO cuts required by science, historical responsibility and sound financial
practices.

The first carbon trading trial phase in 2005-2007 was an abject failure. At 2298 million tons of
CO, the 2007 cap was actually 8.3% higher than verified 2005 greenhouse gas emissions.
Businesses were therefore free to increase emissions – or set emission permits aside for the
next EU-ETS phases. Anxious to avoid having to make short-term investments in emissions
reductions, industry lobbying against higher, effective targets has been extremely effective.
In the current 2008-2012 phase, the average CO cap is 2% lower than 2005 emissions. But
in seventeen out of twenty-member states – including France, Poland and the UK, 2012
caps are still higher than measured emissions in 2005. Overall, twenty-one out of twenty
seven member states sought 2012 emissions caps that were higher than 2005 emissions (with the richest EU member state, Luxembourg, pushing for a 52% increase).

There are now so many unused permits that most industries covered by the Emissions
Trading System (responsible for almost 50% of EU emissions) can legally avoid making any
cuts before at least 2016. What’s more, there is no obligation to reduce emissions in Europe.

Through the United Nations’ Clean Development Mechanism, EU-ETS sector businesses
may invest in projects outside Europe. Known as offsetting, this avoids domestic cuts,
frequently even fails to reduce emissions in developing countries, and may also cause
significant social and environmental problems.

Adding up paltry CO emissions caps and offsetting loopholes reveals a dangerous gap
between science and political reality. The International Panel on Climate Change (IPCC) has
made it plain that 25-40% emissions cuts will only offer a 50% chance of keeping global
temperature increases below 2°C. Within the EU, the Netherlands has already budgeted for
€100 billion to cope with sea level rises of 1 metre. Yet reports are now warning that a 2°C
increase could lead to the tipping point beyond which the Greenland ice cap cannot survive.
This could result in catastrophic 7 metre sea level rises.

In this context, ongoing reliance on the Emissions Trading System is a risk that cannot be
taken. The EU must urgently increase its emissions target to at least 40% - the upper ‘safe’
level set by the IPCC – and ensure that these cuts are domestic. This calls for strong political
will. Rather than depend on the uncertain, ineffective, and unfair Emissions Trading System,
the EU must privilege other forms of action. This includes tougher laws to develop
renewables and increase energy efficiency, as well as carbon taxation and incentives for
public and private investment to pay for emissions cuts.

#  Fossil Fuels Dominate Global Primary Energy Consumption

Significant price differences between regional natural gas markets have driven many European countries to increase coal consumption while decreasing use of natural gas (Source: BP).
Coal, natural gas, and oil accounted for 87 percent of global primary energy consumption in 2012 as the growth of worldwide energy use continued to slow due to the economic downturn. The relative weight of these energy sources keeps shifting, although the change was ever so slight. Natural gas increased its share of global primary energy consumption from 23.8 to 23.9 percent during 2012, coal rose from 29.7 to 29.9 percent, and oil fell from 33.4 to 33.1 percent. The International Energy Agency predicts that by 2017 coal will replace oil as the dominant primary energy source worldwide.
The shale revolution in the United States is reshaping global oil and gas markets. The United States produced oil at record levels in 2012 and is expected to overtake Russia as the world’s largest producer of oil and natural gas combined in 2013. Consequently, the country is importing decreasing amounts of these two fossil fuels, while using rising levels of its natural gas for power generation. This has led to price discrepancies between the American and European natural gas markets that in turn have prompted Europeans to increase their use of coal for power generation. Coal consumption, however, was dominated by China, which in 2012 for the first time accounted for more than half of the world’s coal use.
Global natural gas production grew by 1.9 percent in 2012; the United States (with 20.4 percent of the total) and Russia (17.6 percent) are the dominant producers. Other countries accounted for less than 5 percent each of global output.
In 2012, coal remained the fastest-growing fossil fuel globally,even though at 2.5 percent the increase in consumption was weak relative to the 4.4 percent average of the last decade. China increased its coal use by 6.1 percent. India also saw significant increases in its coal consumption—9.9 percent in 2012. Coal use by members of the Organisation for Economic Co-operation and Development (OECD) declined by 4.2 percent, as an 11.9 percent decline in U.S. consumption outweighed increases of 3.4 percent in the EU and 5.4 percent in Japan.
Oil remains the most widely consumed fuel worldwide, but at a growth rate of 0.9 percent it is being outpaced by gas and coal for the third consecutive year. The OECD’s share declined to 50.2 percent of global consumption—the smallest share on record and the sixth decrease in seven years. This reflects declines of 2.3 percent in U.S. consumption and of 4.6 percent in EU consumption. By contrast, usage in China and Japan rose by 5.0 and 6.3 percent respectively.
Conversely, global oil production grew by more than twice as much as consumption—2.2 percent or 100.1 million tons in 2012. This was mainly due to a rise in U.S. output of 13.9 percent—the highest rate ever. In comparison, Canada, China, and the former Soviet Union saw relatively small increases of 6.8, 2.0, and 0.4 percent respectively.
Consumption of all fossil fuels will likely grow in the future. With increasing shale gas fracking and many countries’ interest in displacing coal generation with natural gas due to the lower greenhouse gas emissions, natural gas use seems well poised to grow. Although some countries are trying to move away from coal use, the incredible coal consumption growth rates in China and India will likely make this the main energy resource in the next few years. Last, even if oil is eventually not the world’s dominant energy resource, its use is expected to grow unless there is a fundamental change in the way the world fuels the transportation sector.
