Chris Huhne speech to the Carbon Show



It is a great pleasure to be here today for the opening of the Carbon Show, and to see such energy and enthusiasm on display.

Emissions trading is an economic curiosity. It is a negative market. For the first time in human history, we are trading in consequences.

That the carbon market exists – and is successful - is testament to just how far we’ve come.
The US National Air Pollution Control Administration first modelled cap-and-trade forty years ago. Ironically, we adopted the ETS to make it easier to sell it back to the US. You can’t win them all.
Over the next forty years, we must hasten our emissions reductions and build a new kind of economy.
Because the next global growth sector is green. Countries – and companies – who do not see the opportunities before them will be left behind.

At this point of the business cycle, people are asking where the jobs will come from.
The answer is here. In this room, today.

The promise of the low-carbon economy is breathtaking. In jobs, in goods and services, and in finance, green opportunities are not just emerging. They are blossoming.

From wind turbines to eco-kettles, low carbon products form a multi-trillion pound market, with growth that outstrips world GDP.

With a vibrant technology and research sector, the UK is well placed to take advantage of the new clean tech markets.

From offshore wind to carbon capture and storage, we are already leading the way.

If we can convert our scientific advantages into hard commercial successes, we can cut carbon and lock-in profits. Making us more secure at home, and more competitive abroad.

We can do our bit to help. The Government is committed to an ambitious programme to reduce emissions – and close the gap between energy supply and energy demand.

Our approach is based on three simple principles.


Firstly, we need to save energy.
Every day, the UK’s housing stock leaks heat – and carbon. Later this year we will launch the Green Deal, a radical scheme to bring our outdated homes up to scratch.

26 million households will qualify for energy efficiency improvements under the Green Deal. And the cost will be offset against future energy bills.

Thousands of jobs insulating homes and businesses will be created across the country, with ripple effects across supply chains and local economies.

A whole new industry will emerge, one that can claw back the ground lost during the recession. This multi-billion pound nationwide retrofit will save money – and energy.

Homes and businesses will make huge efficiency savings. But there is room for improvement in power-hungry industries, too. The CRC Energy Efficiency Scheme is already causing ripples in the sectors which use the most energy.

No-one, least of all this government, wants to burden businesses with extra responsibilities without clear benefit.

We will keep a close eye on the CRC. Making sure it is effective, simple and streamlined; encouraging those industries that need it most. If it can be improved, we will make changes before the next stage in 2013.
Secondly, we need to clean our supply of power.

The replacement of our outdated energy infrastructure, and the creation of new low-carbon power plants, will present real opportunities for British business.

With £200bn of capital needed over the next ten years, investors and manufacturers alike can benefit from the shift to low-carbon power generation.

Again, we will do our bit to help.
The Green Investment Bank will help us catalyse private sector finance, bringing forward a new generation of low-carbon energy production.

By leveraging private finance on behalf of public policy aims, we can spend a little to secure a lot.
The next generation of wind, wave, and waste energy help us get off the oil hook – and onto clean, green growth. So that by the end of this Parliament, we will be the fastest improving European nation when it comes to renewable energy.

Two weeks ago I launched the world’s largest offshore windfarm, at Thanet in Kent. It is a spectacular creation; 300 megawatts of capacity, bringing our offshore total to 5 gigawatts. Each of the 100 turbines is higher than Nelson’s column, and to my mind just as majestic. Within the next decade, industry is aiming for a tenfold increase in capacity.

Few sectors are comfortable making claims like that in the current climate. Even fewer would expect to honour them. But I expect they will.

The growth in renewable power generation and the replacement of our ageing energy infrastructure make a compelling case. Green growth is the best bet for our future prosperity.

It’s also best for the future of our planet. A third of UK emissions come from electricity generation. Conversion losses compound the problem. Burning fossil fuels isn’t just bad for the atmosphere, it’s also an inefficient way of transforming energy.

We need to get the right mix of technologies and energy sources, so that we play to our strengths.
That includes cleaning our existing fossil fuel plants. With strong emissions performance standards, and a commitment to carbon capture and storage pilots.

Some dismiss CCS as a sticking plaster solution to a critical situation. But until we can produce our electricity cleanly, we must minimise the damage done by dirty fuels.

With a new coal powered power plant switching on every week in China, our ability to develop and export CCS on a commercial scale makes environmental and business sense.

Finally, it’s vital that we set out a credible path towards a global emissions deal. That means working with our European partners in support of an ambitious international climate change agenda.
And that is why, together with my French and German colleagues, I have called for a more challenging EU emissions target: a 30% reduction by 2020.

A higher target will strengthen Europe’s intent. Aspiration is important; it tells investors that Europe’s future prosperity is tied to the low-carbon economy.

At the moment, the EU ETS carbon price is not high enough.
It does not provide the long-term certainty investors need to commit to low-carbon generation.
As we announced in the Budget, we will publish proposals this autumn to reform the climate change levy to secure a more effective, more representative carbon price.

That will consolidate our first mover advantage, and open up opportunities for British businesses.
The Coalition agreement is clear: we will seek an ambitious, legally binding global deal on emissions reductions.

Such a deal is unlikely this year. Instead, we will focus our energies on rebuilding political consensus; and getting the right structures in place before the next round of negotiations.
The first step will be to bring emissions offers made since Copenhagen into the UNFCCC process.
Then we can strengthen the measurement, reporting and verification system. So that developing and developed countries have faith that progress is measured fairly and firmly.
And finally, we can clarify the structure and governance of long-term climate finance.

These are practical, achievable steps we can take to firm up the international climate change negotiations, and prepare the ground for a global deal.


  • Action on energy efficiency, to manage our demand.
  • Action on energy generation, to clean our supply.
  • And action on the international stage, to secure a binding legal deal to cut emissions.
  • These are the three principles that underpin our approach.
  • They will drive us toward a new, low-carbon economy.
  • One that is more competitive, more secure, and more sustainable.

Thank you very much.

Funneling solar energy: Antenna made of carbon nanotubes could make photovoltaic cells more efficient



ScienceDaily (Sep. 13, 2010) — Using carbon nanotubes (hollow tubes of carbon atoms), MIT chemical engineers have found a way to concentrate solar energy 100 times more than a regular photovoltaic cell. Such nanotubes could form antennas that capture and focus light energy, potentially allowing much smaller and more powerful solar arrays.

"Instead of having your whole roof be a photovoltaic cell, you could have little spots that were tiny photovoltaic cells, with antennas that would drive photons into them," says Michael Strano, the Charles and Hilda Roddey Associate Professor of Chemical Engineering and leader of the research team.

Strano and his students describe their new carbon nanotube antenna, or "solar funnel," in the Sept. 12 online edition of the journal Nature Materials. Lead authors of the paper are postdoctoral associate Jae-Hee Han and graduate student Geraldine Paulus.

Their new antennas might also be useful for any other application that requires light to be concentrated, such as night-vision goggles or telescopes.

Solar panels generate electricity by converting photons (packets of light energy) into an electric current. Strano's nanotube antenna boosts the number of photons that can be captured and transforms the light into energy that can be funneled into a solar cell.

The antenna consists of a fibrous rope about 10 micrometers (millionths of a meter) long and four micrometers thick, containing about 30 million carbon nanotubes. Strano's team built, for the first time, a fiber made of two layers of nanotubes with different electrical properties -- specifically, different bandgaps.

In any material, electrons can exist at different energy levels. When a photon strikes the surface, it excites an electron to a higher energy level, which is specific to the material. The interaction between the energized electron and the hole it leaves behind is called an exciton, and the difference in energy levels between the hole and the electron is known as the bandgap.

The inner layer of the antenna contains nanotubes with a small bandgap, and nanotubes in the outer layer have a higher bandgap. That's important because excitons like to flow from high to low energy. In this case, that means the excitons in the outer layer flow to the inner layer, where they can exist in a lower (but still excited) energy state.

Therefore, when light energy strikes the material, all of the excitons flow to the center of the fiber, where they are concentrated. Strano and his team have not yet built a photovoltaic device using the antenna, but they plan to. In such a device, the antenna would concentrate photons before the photovoltaic cell converts them to an electrical current. This could be done by constructing the antenna around a core of semiconducting material.
The interface between the semiconductor and the nanotubes would separate the electron from the hole, with electrons being collected at one electrode touching the inner semiconductor, and holes collected at an electrode touching the nanotubes.

This system would then generate electric current. The efficiency of such a solar cell would depend on the materials used for the electrode, according to the researchers.
Strano's team is the first to construct nanotube fibers in which they can control the properties of different layers, an achievement made possible by recent advances in separating nanotubes with different properties.

While the cost of carbon nanotubes was once prohibitive, it has been coming down in recent years as chemical companies build up their manufacturing capacity. "At some point in the near future, carbon nanotubes will likely be sold for pennies per pound, as polymers are sold," says Strano. "With this cost, the addition to a solar cell might be negligible compared to the fabrication and raw material cost of the cell itself, just as coatings and polymer components are small parts of the cost of a photovoltaic cell."

Strano's team is now working on ways to minimize the energy lost as excitons flow through the fiber, and on ways to generate more than one exciton per photon. The nanotube bundles described in the Nature Materials paper lose about 13 percent of the energy they absorb, but the team is working on new antennas that would lose only 1 percent.

Low carbon businesses hail "greenest election"



The 2010 election campaign has left low carbon businesses unsure whether to celebrate the "greenest election" on record or commiserate at the way environmental issues were sidelined by economic concerns.

EU kicks off latest carbon trading crackdown



The EU launched the latest phase of its clampdown on fraud in the carbon market yesterday, banning any trade in "recycled" carbon credits. The move is designed to avoid a repeat of last month's scandal that saw a number of firms purchase illegally traded emission allowances that had already been surrendered by other companies.

01 April 2010 - Press Release - Low Carbon Rewards Launch Today to Save Money for Homes and Businesses



Reducing energy use and small-scale electricity generation across Britain

The introduction today of two carbon cutting Government incentive schemes will see homes and businesses playing a key role in contributing to UK emissions reductions of at least 34% on 1990 levels by 2020 through improved energy efficiency and small-scale low-carbon electricity.
The Government’s Carbon Reduction Commitment Energy Efficiency Scheme (CRC EES) for organisations and Feed in tariffs (FITs) will help to save money on fuel bills, reduce carbon emissions and generate their own low-carbon electricity.
Secretary of State for Energy and Climate Change, Ed Miliband, said:
“From today the rewards for businesses and householders who act to cut their carbon emissions really start to pay off.  It’s no longer simply about doing the right thing for the environment, it’s now a sure-fire financial investment.

“The UK is leading the way in tackling climate change. Organisations and householders can play a central role in leading the move to a low carbon economy whilst saving money on their energy bills.”
The offering to business – CRC Energy Efficiency Scheme
The CRC Energy Efficiency Scheme launched today aimed at saving public and private sector organisations around £1billion per year by 2020 through cost effective energy efficiency measures that are not yet being taken up.
The aim of the CRC Energy Efficiency Scheme is to help change behaviour and will require large public and private sector organisations like supermarkets, hotels, hospitals, local authorities and central government departments, to improve their energy efficiency.
Participants’ performance will be published in the form of a league table.
All revenue raised from the sale of emissions allowances will be recycled back to participants with those who have increased efficiency receiving more of this money. Customers, clients and competitors will also to see that their organisation is a leader in tackling climate change. They will be able to generate further income from selling any unused permits.
Though the scheme officially launches today organisations have until September to register. Businesses can start saving on their bills immediately through implementing cost effective energy efficiency  measures. By 2020 the scheme is expected to have delivered emissions savings of at least 4.4 million tonnes of CO2 per year.
The Department of Energy and Climate Change and the Environment Agency, which will be running the scheme, has hosted more than 115 events to raise awareness about the scheme as well as running regional workshops and speaking events.
The offering to consumers - FITs
Individuals, organisations or businesses in England, Wales and Scotland who install low carbon electricity generation could benefit from FITs:
They will be paid money for every unit of electricity they generate. They will get an extra 3 pence/kWh for every unit they don’t use that is exported to the grid. They can also benefit from a reduced electricity bill where they use the electricity that they generate rather than having to buy all they need from the grid.
A typical 2.5kW, well sited solar PV Installation could offer savings of £140 a year plus earnings of £900 a year.
In addition to providing a contribution to meeting the 2020 Renewable Energy Target, the FITs will enable broad participation of individuals and communities in the shift towards a low carbon economy.
The feed-in tariff is a win-win for consumers. They will be paid for any electricity they generate themselves from low carbon sources and benefit from a cheaper electricity bill.
In Summary
Significant progress has already been made since the Low Carbon Transition Plan was published in July 2009, including in the key sectors of power generation, buildings and industry, and transport. The Government’s legally-binding ‘carbon budgets’ push the pace of change.  UK emissions are already 22% down on 1990 levels.  By 2020 they must be 34% less, on the way to 80% less by 2050.
Government is also setting an example, it is on course for reducing emissions from central Government offices by over 17% by 2011, exceeding the original target of 12.5%. It aims to save up to £300 million through energy saving measures across the public sector.
