Wind turbines china

The world’s top polluter, China, is a surprise leader in clean energy efforts, a study showed Tuesday, outstripping the United States and Japan and leaving Australia lagging far behind.

The Vivid Economics report, commissioned by Australia’s Climate Institute thinktank, showed China was second only to Britain in the value of its incentives to cut pollution from electricity generation.

Britain’s efforts were estimated at 29.30 US dollars per tonne of carbon to China’s 14.20 US dollars, with the United States clocking 5.10, Japan 3.10, Australia 1.70 and just 70 US cents for South Korea.

The six countries account for just under half of all global emissions.

“The Chinese leadership have made a strategic decision that they missed out on the last two industrial revolutions and they don’t want to miss out on the third one,” said Erwin Jackson, director of the Climate Institute, of China’s “surprising” dominance.

“They are now commanding the largest market share of clean energy investment at a global level as a result,” Jackson told AFP.

China’s investment in clean energy topped 35 billion US dollars in 2009 compared with 11 billion in Britain and 18 billion in the United States, and Jackson said it was set to increase tenfold over the next decade.

The main driver of China’s performance was its commitment to shutting down more than 100 small coal-fired power plants for cleaner coal stations by 2011, which the report said would reduce emissions by 15 percent.

It also offered subsidies worth billions of yuan for green energy projects, aiming to generate 15 percent of the nation’s total energy from renewable sources by 2020.

In Japan, 10 major power producers had joined a voluntary scheme aiming to cut emissions by 20 percent of 1990 levels by 2012, a major initiative which accounted for more than half of its clean energy rating.

Variations of an emissions cap-and-trade system were in place in South Korea, Britain, Tokyo, and parts of the United States, the report said.

The study said there were few policies which applied directly to coal, despite the fact it was the major source of fuel and carbon pollution for the six countries.

It also warned that none of the countries was on track to meet reduction targets agreed after last year’s global climate summit at Copenhagen, with Japan lagging worst in relative terms.

Jackson said the report showed that Europe and China were ahead of the game on pollution reduction investment, far outpacing countries such as Australia — the world’s worst per capita polluter due to its heavy dependence on coal.

Without action to price carbon, he said Australia risked falling foul of anti-pollution taxes, with countries such as Japan and India already taxing imports of coal and similar moves foreshadowed in the United States and Europe.

Australian Climate Change Minister Greg Combet welcomed the report, saying a carbon price “will not only provide an incentive to reduce pollution but also … drive this country’s long-term competitiveness”.

The ruling Labor party in Australia, the world’s largest coal exporter, has shelved emissions trading laws after failing to pass them and nearly lost power at August polls, with the eco-minded Greens party winning a record vote share.

Prime Minister Julia Gillard, now at the head of a Greens-backed coalition government, has urged penalties for carbon pollution and formed a cross-party committee to investigate the best way to slash emissions.

Renewable energy technology in South Africa is ready and waiting; it just has to be rolled out.

This was the conclusion reached by the panellists at the second of the Shell Energy Dialogues last Thursday.

The discussion was chaired by CNBC Africa presenter Lerato Mbele and included Wendy Poulton from Eskom; Richard Worthington from the World Wide Fund; Professor Johann Görgens from the University of Stellenbosch; Stuart Fredman from Clean Energy Solutions; and Barry Bredenkamp from the Central Energy Fund. The theme of the evening was “Alternative Energy: Pipeline or Pipedream?”

South Africa has pledged itself to the target of 4% renewable energy by 2013, but the question is whether the country will be able to achieve this goal, given the monopolisation of coal-based power producer Eskom in the local energy market.

“The only way we’re going to achieve a just transition to a sustainable electricity supply is to maximise the role of renewable energy,” said Worthington. “The future will be predominantly and eventually entirely in renewable energy.”

But, warned Bredenkamp, the responsibility for the transformation to renewable energy is not solely the government’s responsibility: “You and me as individuals also have a role to play. There’s a lot of alternative energy that we can use in our own homes.”

South Africa has massive renewable energy potential, with its many hours of sunshine and wind. Developers are keen to get started, but the problem is getting it to the people.

“Who is the developer going to sell [energy] to? You have to be able to transmit it across the national grid,” said Fredman. “Give us access to the national grid and we’ll achieve the energy targets and bring the levelised cost of energy down over the next 10 years.”

Cost issues
Part of the problem of getting people and industry to use alternative energy is the cost.

Fredman explained: “The cost is slightly higher over the short term than [coal-fired power stations] … but as we look over 10, 15, 20 years, the cost comes down to be level with coal, and then significantly lower.”

A factor in renewable energy’s favour has been the recent global economic crisis and the rising costs of oil and other energy.

Görgens said: “The renewable energy debate in the last five years has really picked up momentum because of global economic changes. Economics will always play a very strong role.”

People must look at the long-term benefits instead of the initial cost, added Worthington. “A compact fluorescent lamp will save you a lot of money over its life cycle.

“Don’t look at the cent-for-cent comparison per kilowatt hour for alternative energy as opposed to coal; rather look at the cost of not having energy. What is it going to cost the economy if we don’t do something quickly and run out of coal-fired power?”

Fredman proposed a solution: “We pay two cents an hour for some form of carbon tax and it’s been sitting in the Treasury … At the moment it has a quantum value of about R8-billion. So the money is there to start a reasonably large roll-out of renewables.”

It is important for South Africa to start implementing renewable energy technology as soon as possible, said Bredenkamp. “South Africa is one component of a large globe … Most countries are accelerating their update of alternative energy. These technologies have to be manufactured and the longer we wait, the further behind we get in the queue.”

“We have a very energy-intensive economy,” said Poulton. “We not only have to change our carbon systems, we also need to look at the energy beyond our economy and become more energy efficient.”

The age of cheap electricity in South Africa is at an end. It may pay to consider alternative and renewable energy sources – or to invest in methods of increasing energy efficiency.

Unfortunately, there are several factors working against an easy transition from the Eskom grid to your own little energy island.

Sustainable and renewable energy engineer Frank Spencer, CEO of Emergent Energy, said the immediate problem is that we are in a transition period from cheap to more expensive electricity.

“Our electricity is still too inexpensive to drive behaviour change, but that will change. In addition, our houses are built so poorly that we use a lot of energy to run them, such as poor insulation on geysers, pipes and ceilings, and energy-inefficient appliances,” Spencer said.

“Houses are optimised for upfront costs, not running costs. As with almost every industry, life-cycle costs are seldom considered.”

Getting the best advice on investments in alternative energy sources is not easy, said Spencer. “Most companies are looking to sell some product, which makes it very difficult to get independent advice. Further, there is no reputable accreditation body that I am aware of.”

Nevertheless, Spencer said there is plenty that homeowners can do to reduce their electricity bills immediately.

“Renewables in a sense give you a hedge against long-term electricity prices because you spend most of the money upfront, so you know precisely what your electricity is going to cost you for the next 10 to 20 years – especially with solar water heaters (turning sunlight into hot water) and photovoltaics (turning sunlight into electricity).”

When it comes to installing renewable energy sources for your home, Spencer said the country’s abundant sunlight means wind just cannot easily compete with solar’s life-cycle costs.

“Solar is cheaper upfront for the same amount of energy (kWh) produced, with much less maintenance. Solar water heaters are the cheapest way of producing energy from the sun, but heat pumps (especially solar heat pumps) are also a good alternative. However, energy-efficiency investments will beat all of these.”

“Energy-efficiency investments can have zero payback time – like taking out superfluous light bulbs – to just a few years, for CFL bulbs.

“Solar water heaters and heat pumps have a payback of about five years (with the Eskom subsidy), but this depends on the volume of hot water consumed.

“By combining energy efficiency gas and solar it is possible to get off the grid with a combined payback of less than 10 years,” said Spencer.

solar panels white house

President Jimmy Carter's solar panels were removed in 1986 by President Ronald Reagan

US President Barack Obama is to install solar panels on the White House roof, a move lauded by climate activists as symbolic of the nation’s energy future.

The panels will heat the Obamas’ water and provide some electric power.

In 1979, President Jimmy Carter installed solar panels later removed by Ronald Reagan. George W Bush put panels elsewhere on the White House grounds.

Mr Obama is a supporter of renewable energy but legislation aimed at cutting carbon emissions died in the Senate.

The solar panels are to be installed by the spring.

“Solar panels on one house, even this house, won’t save the climate, of course,” global warming activists 350.org wrote on their website. “But they’re a powerful symbol to the whole nation about where the future lies.”

The move was announced by US Energy Secretary Steven Chu at a conference in Washington on ways for the federal government to improve its environmental performance.

We at www.waterandsolar.co.za want South Africa to start seriously looking now at renewable energy and reduce its need for coal fired power stations.  As individuals we can start in our homes by introducing a greener way of living with greywater systemsrainwater harvesting and solar water heaters.  Together we can start reducing our homes carbon footprint and our need for coal hungry Eskom and municipal water.

SOME pretty strange vehicles, creeping through the Eastern Cape at a snail’s pace, drew curious looks yesterday.

Five teams went past East London on their way to Kokstad for the national 10-day Solar Challenge across South Africa, a race aimed at promoting renewable energy and environment consciousness.

Yesterday, day eight , the teams were on their way back to Pretoria, from where they set off last week Wednesday.

Japanese world champion solar car the Tokai Challenger, with former world rally champion and 1997 Paris Dakar winner Kenjiro Shinozuka at the wheel, against a typically South African background, was the first to travel through the Eastern Cape during the South African Solar Challenge, an alternative fuel vehicle racing competition. It claims a theoretical top speed of 160km/h.

The Dispatch caught up with the 22-person Team DSJ from the German DSJ School in Johannesburg, who passed by at around midday yesterday.

Racing frantically to maintain their third place, behind a Japanese team and a team from Pretoria, they stopped for a short break and to change drivers along the N2 on the way to Butterworth.

Giving their solar-paneled car Sonnenbrand a break, too, the team talked about the excitement of the challenge and competing with more experienced teams .

“There was a lot of interest at school when the invitation to take part arrived. After we secured sponsorship we built our car over five months,” 16-year- old project manager Dimitri Hiestermann said.

With the Japanese Tokai Challenger, which has competed since the inception of the challenge in 2005, in the lead, the teams headed for Kokstad, from where they will be going to Richards Bay.

The race, driven by Pretoria- based Advanced Energy Foundation, challenges teams to take their solar-powered cars through the length and breadth of South Africa.

Teams build their own cars, design their own engineering systems and take them through demanding terrain. “The teams are a mixture of local and international teams from across the world, who compete for prizes, prestige and experience,” the foundation’s Winstone Jordan said.

The vehicles go through gruelling qualifying and technical inspections before the start, Jordan said.

The competition aims at promoting design, management, building and racing solar powered vehicles across South Africa and is held every second year. Each team is escorted by a support team throughout.

“The team spirit is always very high despite a long and tiring day,” Hiestermann said – and despite low points, like when the panels refused to charge the batteries and when their motor burnt out .

From Pretoria last Wednesday, teams raced to Bloemfontein and from there to Cape Town, George and then Grahamstown, from where they left yesterday for Kokstad.

The Tokai Challenger has led the race since last week.

“We have to stick to the speed limit, but the Tokai Challenger has reached a speed of 145km/h and can theoretically clock 160km/h. It’s the fastest solar-powered car in the world and we’re very proud of it,” Professor Hideki Kimura of the University of Tokai told The Herald in Plettenberg Bay earlier this week.

After Richards Bay, they head for Badplaas – and then return to Pretoria on Saturday for prize-giving.

“We plan on improving our design and entering every challenge from now on,” Hiestermann said.

South Africa – The department of energy launched the start of its Renewable Energy Procurement Project under the Renewable Energy Feed-in Tariff (REFIT) Programme.

It also launched its Request for Information (RFI).

Acting deputy director-general in the department Ompi Aphane said: “One key element of [a proposed renewable energy] programme will be the entrepreneurship and innovativeness of South Africa’s industrial and financial sectors, and another element will be the development by the government of appropriate policies and frameworks that would encourage and guide the private sector.”

He said South Africa had a high level of renewable energy potential.

The focus on renewable energy was established in 2003 with the launch of the Renewable Energy White Paper which targeted four percent (10, 000GWh) of renewable energy by 2013, he said.

The department had identified the need to “stimulate” the renewable energy industry in South Africa.

In preparation for the REFIT programme the department initiated a review of areas that would ensure an investor-friendly environment.

There was a review and evaluation of the current enabling regulatory and legal environment, of the institutional structures and decision-making processes, and the development of a set of standardised procurement documentation.

The RFI was aimed at potential private developers of renewable energy projects.

These were wind, solar, biomass, biogas, small hydropower and landfill gas, and co-generation projects.

The department had entered into a Memorandum of Agreement signed by itself, the Treasury and the Development Bank of Southern Africa (DBSA) on Independent Power Producers (IPPs).

“Our intention in releasing this Request for Information (RFI) is to get potential developers of renewable energy projects to indicate their interest in – or to provide information on – the progress of their projects in South Africa under the Renewable Energy Feed-In Tariff (REFIT), said Aphane.

“In short, we hope that the RFI will provide us with enough information to assess the progress developers have made since the announcement of the REFIT programme as well as the readiness of the market to enter into intensive procurement and fast-track negotiation processes.”

Submissions from other potential participants included municipalities, financial institutions and technology and equipment suppliers.

We at www.waterandsolar.co.za want South Africa to start seriously looking now at renewable energy and reduce its need for coal fired power stations.  As individuals we can start in our homes by introducing a greener way of living with greywater systemsrainwater harvesting and solar water heaters.  Together we can start reducing our homes carbon footprint and our need for coal hungry Eskom and municipal water.

rainwater harvestingRainwater harvesting can (a) assure an independent water supply during water restrictions, that is though somewhat dependent on end use and maintenance, (b)usually of acceptable quality for household needs and (c) renewable at acceptable volumes despite forecast climate change (CSIRO, 2003). It produces beneficial externalities by reducing peak stormwater run off and processing costs. RH systems are simple to install and operate. Running costs are negligible, and they provide water at the point of consumption.

Rainwater harvesting can be adopted in cities to supplement the city’s other water supplies, to increase soil moisture levels for urban greenery, to raise the water table through artificial recharge, to mitigate urban flooding and to improve the quality of groundwater. In urban areas of the developed world, at a household level, non-potable uses of harvested rainwater include bathroom (i.e. shower/bath/basin), flushing toilets and washing laundry. Indeed in hard water areas it is superior to municipal water for laundry because of its compatibility with detergents and soaps. Rainwater may require treatment prior to use for drinking, depending on anthropogenic (e.g. vehicle exhaust) and natural (e.g. Coal.) contaminants.

In New Zealand, many houses away from the larger towns and cities routinely rely on rainwater collected from roofs as the only source of water for all household activities. This is almost inevitably the case for many holiday homes.

Rainwater harvesting is particularly relevant in areas such as the Garden Route where relatively good rainfall is experienced during summer and winter but due to the towns growing at a rapid rate the dams cannot cope.  Water shortages have become more frequent in many towns and cities around South Africa.

Huge growth at largest wind farm

wind turbines Generating capacity at Whitelee will increase by more than two thirds

A massive expansion is to take place at Europe’s largest onshore wind farm, which is situated in East Renfrewshire.

ScottishPower Renewables is to add another 75 turbines to Whitelee wind farm on Eaglesham Moor by 2012.

This will bring the number of turbines on site to 215 – raising electricity generating capacity by two thirds.

The 140 turbines currently at the wind farm, to the south of Glasgow, can produce enough electricity to power 180,000 homes.

The expansion will see its generating capacity increase from 322MW to 539MW – enough to power about 300,000 homes.

The power utility said yesterday that it would start the procurements in October or November, before a planned independent power purchasing body to be created to negotiate energy deals separately from Eskom, was created.

The utiliy’s Yousuf Haffejee said the procurements, expected to add 1025MW to the national grid, would take up to a year to be completed.

The power-generating plants established by the projects will be commissioned by 2012-2013. Continue reading »

Do your part towards sustainable living by following ten easy tips on saving water.

Water is becoming a scarce commodity and is just as important as recycling waste or saving energy. Save water by:

1. Fixing any leaks that may occur in your home. Ensure that all your taps are leak free or get leaking taps fixed immediately.

2. Do not pour water down the drain if it can be used for other purposes like cleaning or gardening.   Best of all install our grew water system so any water going down the drain feeds into a tank for watering the garden.

3. Check for toilet tank leaks – pour food colouring in the tank and you’ll be able to spot them.

4. Avoid flushing your toilet unnecessarily – dispose of all tissues and sanitary towels by other means. The more you flush the more water is wasted.   Install our multi-system to minimise water waste.

5.  When washing dishes use a bowl of water rather than letting the water run.

6. When showering, don’t take long showers. Keep them short and sweet.

7. To save water you can also switch your shower head to an aerating fixture which mixes air into the flow to keep the pressure high.

8. Do not defrost meat or other food packages under running water. Defrost it overnight or use the defrost setting on your microwave.

9. Don’t leave the water running when washing your face or brushing your teeth. Use a glass to rinse or gargle.

10.   Last but by no means least – install our Water Rhapsody Grand Opus and Grey Water system for the best possible solution.
