Low carbon Leeds City Region would ’save money and create jobs’

Wednesday, January 11th, 2012

Hopes of turning the Leeds city region into a ‘low carbon area’ have been given useful underpinning by an academic study which shows how cutting energy bills could be both profitable and create jobs.

The two-year project by four universities offers three levels of investment in largely conventional energy-saving measures – everything from park-and-ride schemes to solar panels – which would pay for themselves over terms ranging from four to seven-and-a-half years.

The most modest would cut £1.2 billion from the annual £5.4 billion energy bill for the region, which has a population of 3,000,000 and includes Barnsley, Bradford, Calderdale, Craven, Harrogate, Kirklees, Leeds, Selby, Wakefield and York. The most ambitious would cut £1.71 billion but need £13.03 billion investment rather than the £4.9 billion needed for the smallest scheme.

Raising such sums in current circumstances is recognised as the principal challenge by the academics, led by Prof Andy Gouldson of the University of Leeds which collaborates in the Centre for Low Carbon Futures with the universities of York (co-authors of the report), Hull and Sheffield. The report acknowledges:

Transition depends on political and social capital as well as financial capital.The levels of ambition, investment and activity needed to exploit the available potential are very significant indeed. Enormous levels of investment are required, along with major new initiatives with widespread and sustained influence in the domestic, commercial and industrial sectors.

And, of course, we need to think about some major innovations, particularly in stimulating the supply of and the demand for major investment resources. We need to think about innovative financing mechanisms, based on new forms of cost recovery and benefit sharing and new ways of managing risk. And we need to develop new delivery mechanisms that can stimulate and sustain demand for investment in low carbon options by overcoming the many potential barriers to change.

The study makes a start on achieving this aim by using realistically pessimistic data in its economic modelling to show how low carbon status would save money. Paying the current energy bill, for instance, sends ten percent of all locally-generated income out of the region, a sum forecast to grow in the next decade.

Prof Gouldson says:

The business case for major scale investments in energy and carbon management is very strong. If local government can underwrite early stage investments, as is happening in some places, then major flows of private sector investment can be secured. Investments can come from institutional investors such as pension funds, or in the near future through the Green Deal, the Green Investment Bank or Energy Company Obligations. The direct economic reasons for securing investments from sources like these are strong enough – but the wider economic, social and environmental benefits make the business case even more compelling.

Interestingly, the major property development proposed for one of Leeds city centre’s last ‘holes’, the area north of the Lower Headrow around the old Lady Lane Methodist chapel, includes a low-carbon energy centre to power £600 million worth of offices, restaurants and shops.

The chief executive of Leeds city council, Tom Riordan, welcomes the data as realistic ammunition against inevitable sceptics in hard times. He tells the Yorkshire Post:

There’s been a feeling in some quarters that in difficult times we’ve got to forget about ‘nice to do’ things like tackling climate change. But the headlines that come out of this study – basically that we could reduce our carbon emissions by a third through purely profitable activities, and at the same time create 1,000 jobs per year – are very impressive.

What this report demonstrates very clearly is that rather than being a ‘nice to do’, this is a ‘must do’ for an economy which wants to become more competitive and at the same time help its poorest people into jobs and to cope with very difficult and stretching financial conditions.

Another advantage is that low carbon status has the support of the Government, which included Leeds city region a year ago in a list of nine pilot areas. The others chosen in the aftermath of the Stern Review on climate change are Bristol, Bournemouth Poole and Dorset, Haringey, Manchester, Northumberland, Nottingham, Oxford and Plymouth.

Cornwall issues tender for Solar Power Plants

Wednesday, January 4th, 2012

Forget the Sahara. Is Cornwall the new solar power capital? A solar goldrush may be just about to emerge as the Cornwall Council has issued a Public Tender Notice for a series of solar power plant plans. The Council says it has posted this notice to advertise its intention to establish a framework agreement for contractors to be appointed for the design, build, operation and maintenance of solar energy generation projects located within the UK regions of Cornwall, Plymouth and Devon.

The general scope of works will involve the design and construction of the entire solar energy generation system, including the associated works to ensure it is connected to the electricity grid and/or any consumer connections. The works will also include the operation and maintenance of the solar energy generation projects to ensure they are kept in working order and maintain their expected energy generation outputs.

The type and range of projects intended to be procured under this framework agreement will range from large-scale solar parks to smaller scale commercial and or domestic installations. The projects called-off under this framework will vary in terms of their electricity generation outputs from an estimated 0.01MW to 5MW.

The first project, named the Kernow Solar Park, to be procured under the Framework will be a ground-based photovoltaic installation, located within close proximity to Newquay Airport in Cornwall, capable of achieving a maximum 5MW output.

Full details of the solar energy generation projects framework agreement will be disseminated to the shortlisted tenderers as part of the Invitation to Tender stage.

In mid-November, Cornwall Council leader Alec Robertson wrote to Energy Minister, Greg Barker to reaffirm the area’s commitment to renewable energy generation. The letter describes the potential problems which could be caused by cutting the feed-in tariffs and also outlines the council’s argument for large-scale solar.

“As part of our ambitious and innovative approach to renewable energy we have developed separate and specific teams responsible for our regulatory function and the facilitation of Cornwall’s green ambitions,” said Robertson.

“It is the council’s belief that the development of ground-based solar PV will provide substantial opportunities to drive the market price down for PV in the UK.”

Feed-in tariff halved for solar PV – act now to reap benefits

Friday, November 4th, 2011

Solar panels biggest earning contributor, the feed-in tariff is to be halved as of 12th December 2011. Although solar panels, with their ability to reduce electricity bills and CO2 emissions, have only become hot news over the past year or so, the Government has announced plans to cut the subsidy from 43p to 21p meaning investors will earn only half of the money that is currently up for grabs.

How does solar work?

When installed, solar panels catch the sun’s rays and absorb solar energy. When harnessed using renewable energy technology, solar panels enable you to generate your own electricity.

Benefits

Solar panels have a number of benefits. Aside from reducing investors’ carbon footprint, there are three main areas where solar panels can make you money.

Free electricity

The energy you generate via solar panels is immediately available to you free of charge. It does not get drawn through your electricity meter, so reductions in your electricity bill are achieved from the date of install.

Get paid for the electricity you generate

This is one of the ways where the feed in tariff (FIT) comes into play. Under the current subsidy, you can be paid for the electricity you generate, whether you use it yourself or not. At present, the Government pay 43.3p to home owners for every unit of electricity that is generated, but recent reports have revealed this will be cut to 21p as of 12th December 2011. A cut meaning only half the amount of money can be earned using solar PV.

Sell electricity back to the grid

Aside from being paid for the electricity you generate, you can also be paid for any excess electricity you sell back to the grid. This equates at 3.1p for every kWh of electricity that is sold back.

India sets out ambitious solar power plan to be paid for by rich nations

Wednesday, August 5th, 2009

India plans to generate 20GW from sunlight by 2020, putting green energy targets of developed nations in the shade.

India has decided to push ahead with a vastly ambitious plan to tap the power of the sun to generate clean electricity, and after a meeting chaired by the prime minister, Manmohan Singh, it wants rich nations to pay the bill.

Although India has virtually no solar power now, the plan envisages the country generating 20GW from sunlight by 2020. Global solar capacity is predicted to be 27GW by then, according to the International Energy Agency, meaning India expects to be producing 75% of this within just 10 years.

Four-hundred million Indians have no electricity and the solar power would help spark the country’s development and end the power cuts that plague the nation. It would also, say some analysts, assuage international criticism that India is not doing enough to confront its carbon emissions. It is currently heavily reliant on highly polluting coal for power.

Solar Industry: No Breakthroughs Needed

Wednesday, August 5th, 2009

The solar industry says incremental advances have made transformational technologies unnecessary.

The federal government is behind the times when it comes to making decisions about advancing the solar industry, according to several solar-industry experts. This has led, they argue, to a misplaced emphasis on research into futuristic new technologies, rather than support for scaling up existing ones. That was the prevailing opinion at a symposium last week put together by the National Academies in Washington, DC, on the topic of scaling up the solar industry.

Cheaper solar: First Solar’s improvements in manufacturing photovoltaics have helped lead to big drops in cost. A worker at a First Solar factory in Frankfurt, Germany, moves one of the company’s solar panels.

The meeting was attended by numerous experts from the photovoltaic industry and academia. And many complained that the emphasis on finding new technologies is misplaced. “This is such a fast-moving field,” said Ken Zweibel, director of the Solar Institute at George Washington University. “To some degree, we’re fighting the last war. We’re answering the questions from 5, 10, 15 years ago in a world where things have really changed.”

Cheaper Solar Thermal Power

Thursday, July 30th, 2009

Stirling Energy Systems (SES), based in Phoenix, has decreased the complexity and cost of its technology for converting the heat in sunlight into electricity, allowing for high-volume production. It will begin building very large solar-power plants using its equipment as soon as next year.

The company is currently building a 1.5-megawatt, 60-unit demonstration plant that will use the company’s latest design. Stirling expects to finish that project by the end of the year. It also has contracts with two California utilities to supply a total of 800 megawatts of solar power in Southern California. The first of the plants that will supply this power could be built starting the middle of next year, pending government permits and loan guarantees from the U.S. Department of Energy (DOE).

The projects are part of a resurgence in what’s known as solar thermal power. Various solar thermal technologies were developed starting in the 1970s, but a breakdown in government funding and incentives caused them to stall before they reached a scale of production large enough to drive down costs and allow them to compete with conventional sources of electricity. “It was a classic problem with solar. The market support to bring solar to high volume wasn’t there,” says Ian Simington, the chairman of SES and chief executive of the solar division of NTR, a company based in Dublin, Ireland, that bought a controlling share of SES last year.
