Solar wars threaten climate fight

Amidst gloomy news in the deteriorating climate change situation is this bright spark – the cost of solar energy has been going down dramatically.


 THE source of clean and renewable energy is seen as one of the major saviours that could help power the world without emitting greenhouse gases.

The drawback is that solar energy has traditionally been more expensive to use than carbon-intensive coal or oil.

But in recent years solar power has become much cheaper. Energy experts predict that its cost could match that of conventional fuels in the next few years in some areas.

Solar cell prices have been falling, from US$76 (RM235.52) per watt in 1977 to about US$10 (RM30.99) in 1987 and only 74 cents (RM2.29) in 2013. Between 2006 and 2011, Chinese cell prices dropped 80% from US$4.50 (RM13.95) per watt to 90 cents (RM2.79) per watt.

Factors for this include a drop in price of the main raw material polysilicon (due to oversupply), increasing efficiency of solar cells, manufacturing technology improvements, economies of scale and intense competition.

The use of solar energy has shot up as the cost goes down. Global installed capacity jumped by 28.4 gigawatts (one gigawatt is 100,000 megawatts) in 2012 to reach 89.5GW. The 100GW milestone will be crossed some time this year.

All this is good news for the fight against climate change. Now comes the bad news.

The growing global demand has prompted the rise of solar panel manufacturers, and the competition is fierce, with a number of companies facing closure. China’s biggest solar energy company Suntech is in serious trouble.

But China has even bigger problems. The United States government, receiving complaints from US solar panel manufacturers, has slapped high anti-dumping tariffs on Chinese imports.

Now the European Commission also plans tariffs averaging 47% on Chinese solar products which it claims are selling below cost.

China is taking these threats seriously. Premier Li Keqiang in a visit to Europe last week took up the issue with European leaders.

Senior trade officials say China will retaliate. A full-scale trade war is thus imminent.

In a surprise turn of events, Germany and 16 other European countries have told the European Commission they are against its move.

But EC Trade Commissioner Karel De Gucht will apparently still slap on the tariffs provisionally, which is within his power to do.

So the solar wars between China with Europe and the US will likely proceed. This is a real pity, as the commercial interests of the countries are coming in the way of rapid progress in solar energy and the fight against climate change.

The expansion of the solar panel industry in China has played a crucial role in getting prices down, making solar energy more and more competitive, and driving its explosive growth.

Yes, China subsidises and promotes its solar industry. But the US and Europe also provide massive subsidies and supports.

The US has provided its solar companies with loan guarantees, research grants and tax deductions including investment tax credits and accelerated value depreciation.

European countries have given subsidies to consumers using solar energy, and incentives to producers including through the feed-in tariff scheme, in which solar energy providers are paid prices higher than what is charged to electricity users with the price difference being met by governments.

Without the subsidies, the solar industry would not have grown. Trade protectionist measures taken by one against the other, or by all against others, would be a recipe for disaster – for trade, the solar industry and the environment.

Well known solar energy advocate and chairman of Solarcentury Jeremy Leggett uses the following analogy to illustrate the trade war: “A planet faces an asteroid strike. Its inhabitants manufacture rockets with which to head off the threat. But, as the rock nears, they descend into international bickering over who pockets what from rocket-making.”

No one wins in this trade war, because of global solar supply chain, explains Leggett. Solar ingots, the upstream feedstock, are mostly made in Europe and America. The midstream products, cells and modules, are mostly made in China.

If China is hit on the mid-stream products it exports, it could retaliate with tariffs on the upstream products it imports.

For example, in Europe, the tariffs against China would wipe out thousands of jobs because most are not in manufacturing but in the companies that install the modules, regardless of where they are made.

The solution, he adds, is for the leaders of the few countries where most solar panels are manufactured to make a deal that coordinates the subsidies required in the various parts of the solar chain, and which is required for the few years that some countries need to bring the price of solar energy to parity with that of conventional energy.

An apt conclusion is made by Leggett: “The world will have to embrace common security on a bigger scale. Engaging in international competition while clinging to the illusion that markets always work will never solve our common problems of energy insecurity, poor air quality and resource depletion, never mind development. We will keep on maiming industries that can save us.”

A house built on smart ideas with earning power

A house built on smart ideas

WITH cool breeze blowing into his house which is also basking in ample natural light, retiree Tan Vait Leong does not need to switch on the lights or air conditioner during the day.

Even at noon, the 56-year-old’s bungalow at Puncak Bukit Mutiara in Pearl Hill is still cool, thanks to the environmentally-friendly and open concept design of the house.

“The planning of the design of the house started five years ago, while construction of the property took three years to complete.

“I would draw up the designs and concepts for the house while I was at airports or in planes, as I travelled frequently for work.

“I enjoyed the process, as it was also an outlet for me to destress,” said the former vice-president of a multinational company.

Having spent a substantial amount of time travelling, the father-of-four said it was only right that he designed his house ala-resort style so he would not “need to go for holidays anymore”.

One of the special features of the house is the photovoltaic (PV) solar panel fixed on the roof, which Tan had obtained through the National Suria 1000 programme to generate power from solar energy.

With that, his household is automatically enlisted under the newly launched feed-in-tariff (FiT) programme where Tenaga Nasional Bhd will buy back power generated from the PV solar panel.

Currently, the PV electricity subsidised about 20% of the household’s total electricity intake while Tan pays about RM700 monthly for his power bill.

“With the FiT, I might not have to fork out a single sen for my electricity bill,” he said yesterday.

A tour around the handsome house with a built-up area of 8,000sq ft shows there are five spacious rooms, four bathrooms, an infinity pool with a view overlooking the sea which is also connected to the living room and master bedroom, an indoor fish pond, a kitchen, a family room, a study room, a living room, an outdoor deck as well as a cosy playroom for Tan’s 10-year-old twin daughters.

Aptly named after Tan’s wife, Foo Sin Gein, 54, he said his home Gein Villa was constructed to blend into existing green environment where the big trees around are spared from the axe.

“I don’t spend money on landscaping. The trees shed leaves seasonally but it is part of the feature of the house. I don’t understand the reasons behind cutting down trees if people want to build houses on the hillside.

“Well there are occasions where our ‘special guests’ — monkeys, squirrels and bats will pay a visit but we don’t harm them as they are not aggressive, just playful,” he said.

There are no excessive furniture in the house, with only the walnut and cherry flooring along with salvaged chengal wood which Tan used to lay the staircase and kitchen tabletop.

“I also use the hollow bricks that were left over from the construction as display shelves,” he said.

“We water the plants with water from the fish pond, and we keep plants at the pool and the filter tub to absorb the nitrate.”



Retiree who still has earning power

GEORGE TOWN: While most people have to pay for their electricity, a 56-year-old retiree is looking forward to selling it to Tenaga Nasional Bhd.

And Tan Vait Leong (pic) simply can’t wait to be paid by the utility giant for the power generated from his photovoltaic (PV) solar panels fixed on the roof of his Tanjung Bungah home.

Believed to be among the first consumers in Penang to obtain the PV under the National Suria 1000 programme to generate power from solar energy, his household is automatically enlisted under the newly launched feed-in-tariff (FiT) scheme.

“This is a blessing in disguise. I have always been conscious about the environment and had incorporated recycling and green ideas into my daily life.

“With this, I might not have to fork out a single sen for my electricity bill,” he said excitedly at his double-storey bungalow at Puncak Bukit Mutiara in Pearl Hill.

The former mechanical engineer said the PV electrivity subsidised about 20% of electricity usage for his sprawling premises with a built-up area of 8,000sq ft (743.22sq m).

Currently, the father-of-four forks out about RM700 monthly for his power bill.

Tan also maintains an open concept for his five-room bungalow where good air circulation keeps the environment cool while ample natural light through glass panels brighten up the interior.

“The swimming pool is part of the house while the indoor fish pond keeps the home cool and is low maintenance too.

“I don’t need to switch on the lights or air-conditioners at all during the day while I do keep several floor fans on,” he added.

Launched last week, the FiT allows individuals or non-individuals to sell electricity generated from renewable energy sources back to power utility firms at a fixed premium price for a specific duration.

The four renewal energy sources that are eligible for FiT are biogas, biomass, small hydropower and solar photovoltaic.

Currently, the rate Tenaga Nasional Bhd (TNB) pays to renewable power producers is 21 sen per kWh
Concurrently, the average domestic rate that consumers pay to TNB is 27.6 sen per kWh.

With FiT, consumers can install their own solar modules at home and earn a secondary income.

Under the Renewable Energy Act 2011, consumers who installed capacity up to and including 4 kWp (kilowatt peak) would be paid a FiT of RM1.23 per kWh.
