Carbon Emissions Falling Fast as Wind and Solar Replace Fossil Fuels

Carbon Emissions Falling Fast as Wind and Solar Replace Fossil Fuels

Europe’s greenhouse gas emissions are falling fast, mainly because of the rapid spread of the wind turbines and solar panels that are replacing fossil fuels for electricity generation.

European Union (EU) data shows that once countries adopt measures to reduce greenhouse gases (GHGs), they often exceed their targets—and this finding is backed up by figures released this week in a statement by the United Nations Framework Convention on Climate Change (UNFCCC).

The Convention’s statistics show that the 37 industrialized countries (plus the EU) that signed up in 1997 to the Kyoto Protocol—the original international treaty on combating global warming—have frequently exceeded their promised GHG cuts by a large margin.

Beacon for governments

The UNFCCC statement says, “This is a powerful demonstration that climate changeagreements not only work, but can drive even higher ambition over time.”

“The successful completion of the Kyoto Protocol’s first commitment period can serve as a beacon for governments as they work towards a new, universal climate change agreement in Paris, in December this year.”

In the EU, the leading countries for making savings are Germany, Sweden, France, Italy and Spain, which account for two-thirds of the total savings on the continent. But most of the 28 countries in the bloc are also making progress towards the EU’s own target of producing 20 percent of all its energy needs from renewables by 2020. It has already reached 15 percent.

Part of the EU plan to prevent any of the 28 member states backsliding on agreed targets to reduce GHGs is to measure every two years the effect of various policies to achieve the reductions.

All states have to submit details of savings achieved through the introduction of renewables in electricity production, heating and cooling systems and transport.

Because of the time taken to compile the figures, the latest report from the EC Joint Research Center goes up only to 2012. However, it shows that each year in the three years up to the end of 2012 GHGs emitted by the EU fell by 8.8 percent as a result of replacing fossil fuels with renewables.

Two-thirds of the savings came from the widespread introduction of wind and solar power. Renewables used for heating and cooling achieved 31 percent of the savings and transport 5 percent. Most transport renewables came from the use of bio-fuels instead of petrol and diesel.

Measuring the progress towards targets is vital for mutual trust between nations in the run-up to the Paris climate talks. It also gives politicians confidence that they can make pledges they can keep.

Ambitious goal

The knowledge that the EU is likely to exceed its target of a 20 percent reduction of all emissions on 1990 levels by 2020 has led ministers to a more ambitious goal—total reductions of 40 percent by 2030. A large part of this will come from the installation of more renewables and energy-efficiency measures.

Across Europe, emissions vary widely from country to country, with Germany having the highest and Malta the lowest. Germany also had the greatest absolute reduction of emissions—a total drop of 23 percent on 1990 levels by 2012.

The highest emissions per capita were in Luxembourg (20 tons of carbon dioxide per person), followed by Estonia (12.7), the Czech Republic (10.2), Germany (9.8) and the Netherlands (9.7).

Just five member states—Germany, Poland, the UK, Italy and Romania—together produced two-thirds of the EU’s emissions in 1990. The only change by 2012 was that Romania had been overtaken by Spain.

Michael Pollan’s Food Rules

Michael Pollan’s Food Rules

Based on Michael Pollan’s talk “Food Rules” given at the RSA, this animation was created in the context of the RSA/Nominet Trust film competition. Using a mixture of stop-motion and compositing, our aim and challenge was to convey the topic in a visually interesting way using a variety of different food products. We made a little table top set up at home and worked on this a little over three weeks.

Another Breakthrough in Hydrogen Energy Challenges Fossil Fuel Dominance

Another Breakthrough in Hydrogen Energy Challenges Fossil Fuel Dominance

Another Breakthrough in Hydrogen Energy Challenges Fossil Fuel Dominanceby Alex Pietrowski

Researchers at Virginia Tech have developed a new process that extracts large quantities of hydrogen gas from plants in arenewable and eco-friendly way, offering us another potential alternative to ending our dependence on fossil fuels.

After 7 years of research, Y.H. Percival Zhang, an associate professor at the College of Agriculture and Life Sciences and the College of Engineering at Virginia Tech, and his team have developed a new method of using customized enzymes to produce high quantities of hydrogen out of xylose, a simple sugar present in plants.

Zhang and his team have succeeded in using xylose, the most abundant simple plant sugar, to produce a large quantity of hydrogen that previously was attainable only in theory. Zhang’s method can be performed using any source of biomass.

This new environmentally friendly method of producing hydrogen utilizes renewable natural resources, releases almost no zero greenhouse gasses, and does not require costly or heavy metals. Previous methods to produce hydrogen are expensive and create greenhouse gases. [Science Daily]

Hydrogen fuel has the potential to dramatically revolutionize the automobile market and reduce ourdependence on fossil fuels. Vehicle manufacturers are already developing cars that run on hydrogen fuel cells, which do not produce as many pollutants as regular gasoline cars. Currently in the US, the transportation sector produces 82% of total CO2 emissions in the country.

EIA estimates that U.S. gasoline and diesel fuel consumption for transportation in 2011 resulted in the emission of about 1,089 and 430 million metric tons of CO2 respectively, for a total of 1,519 million metric tons of CO2. This total was equivalent to 82% of total CO2 emissions by the U.S. transportation sector and 28% of total U.S. energy-related CO2 emissions.

Zhang’s method of hydrogen production will need to find its way into commercial markets, which could happen in about 3 years, before any significant impact on the alternative energy market is possible. Even though Zhang’s process addresses the previous obstacles to hydrogen gas production, including high process costs, greenhouse gas emissions, and low quality of the end product, large investment in technology development and infrastructure would still be necessary to transition to hydrogen fuel cars.

“The potential for profit and environmental benefits are why so many automobile, oil, and energy companies are working on hydrogen fuel cell vehicles as the transportation of the future,” Zhang said. “Many people believe we will enter the hydrogen economy soon, with a market capacity of at least $1 trillion in the United States alone.”

“It really doesn’t make sense to use non-renewable natural resources to produce hydrogen,” Zhang said. “We think this discovery is a game-changer in the world of alternative energy.” [Science Daily]

A future where renewable energy replaces energy production using fossil fuels is inevitable. Some have gone as far as to illustrate that we have the potential to make this shift in less than 20 years, for example, Mark Z. Jacobson of Stanford University and Mark A. Delucchi of the University of California, published a study that shows it is possible to power New York State using only renewable sources by 2030.

Nevertheless, governments’ support of traditional energy production via fossil fuel subsidies, which amount to $1.9 trillion per year, as reported by the International Monetary Fund, is one of the main obstacles to the growth of alternative energy sources. The IMF estimates that $480 billion of the total is comprised of direct subsidies, which have the goal of making petroleum products more affordable.

A fossil fuel subsidy is any government action that lowers the cost of fossil fuel energy production, raises the price received by energy producers or lowers the price paid by energy consumers. There are a lot of activities under this simple definition—tax breaks and giveaways, but also loans at favorable rates, price controls, purchase requirements and a whole lot of other things. [Oil Change International]

The remaining $1.4 trillion are comprised of “externalities”: “the effects of energy consumption on global warming; on public health through the adverse effects on local pollution; on traffic congestion and accidents; and on road damage.” (IMF) Current energy policies are established in such a way that fossil fuel companies do not pay for any of these “externalities”, and thus leaving these industry costs to be indirectly subsidized by governments.

Here are some more statistics about the energy subsidies in the US:

“…between 1994 and 2009 the U.S. oil and gas industries received a cumulative $446.96 billion in subsidies, compared to just $5.93 billion given to renewables in those years. (The nuclear industry, by the way.  received $185 billion in federal subsidies between 1947 and 1999.)”

With such policies in place, heavily influenced by large multi-billion dollar companies with strong government ties, is a rapid change towards renewable energy even possible? Are we ready to challenge our policies to shift financial support from harmful and damaging energy production to renewable technologies, and change our own behaviors to create a cohesive movement towards a cleaner and safer planet?

If breakthroughs in technology can offer salient alternatives to the economic stranglehood fossil fuels has on our economy, then we may realize a future of clean energy. One thing is certain, however, without practical alternatives there is no chance of changing the momentum behind extraction based energy toward clean energy.
