Energy crisis….what would you do?

September 14, 2009

I have a question for you to ponder. There is no correct answer to this question, every one can have their own opinion about it.

Imagine you are the leader of a country. Your country is faced with a major energy crisis. Your supply of oil (and other non-renewable energy sources) is about to run out. You have to make a decision as to what you are going to do.

Please leave a comment about what you would do in order to keep your country “running.” In order to leave your thoughts on this question you are going to have to leave a comment on this blog post. While you are writing your comment you need to think about your answer, and why you think what you think. Explain your ideas using lots of detail.

European wind power producers are calling for billions of euros in investments to generate energy from wind turbines planted in the sea.

Click on this link to see the article about windmills. This is probably the most important paragraph:

Offshore wind is expensive and can only compete with fossil fuels when oil hits record highs, such as the $US147 ($A170.32) a barrel it was trading at last July. In its defence, Kjaer said the costs of wind power are fixed – unlike fluctuating market prices for coal or gas.

What’s your Ecological Footprint?

September 9, 2009

6CB Visited the website Zerofootprint Kids Calculator to see what their Ecological Footprint was. They also compared their results with the averages from other countries.

Read their comments to see what they found out and how they reflected.

Click on the picture to test your Ecological Footprint – are you using the earths energy and other resources in a sustainable manner?

Kids eco

The people in Canada average the need for 4.9 earths to continue their lifestyle.

The people in USA average the need for 5.3 earths to maintain their lifestyle.

The people in India average 0.4 earths (that’s less than on whole).

Do you think this is fair? Take the poll below:

Green Fuels to make up 20%

September 7, 2009

Click on this picture to go to the article. By 2023 Thailand expects to be having 20% of its energy needs met by ‘Green Fuels’.

Do you think 20% is enough or should we try to get even more renewable energy to meet our needs? Read the article and leave a comment.

Pig waste to make electricity

Pig manure sweet money for Thai farmer

NAKHON PATHOM, Thailand (Reuters) – For Thai pig farmer Ong-Arj Suwunnatee, going green was not only good for business and the environment, it came as a welcome relief to his neighbors.

“Back in the old days, people knocked on my door and complained about the smell,” said Ong-Arj, who owns 4,000 pigs in Nakhon Pathom, 55 km (35 miles) west of Bangkok in the heart of Thailand’s hog country.

“Now? They hardly even notice. People around here are happy to show you how to get to my house,” Ong-Arj told Reuters after showing off a biogas plant he designed himself during a tour of his 9.7 hectare (24 acre) enclosed pig farm.

Using a simple system to capture the methane gas from pig manure and convert it into electricity, Ong-Arj slashed his power bill by thousands of dollars and cut gas emissions that harmed the environment and annoyed his neighbors.

“The smell has gone. The flies have gone and I have more cash in my pocket,” said the 35-year-old father of two.

Thailand has begun to embrace biogas — created from sewage, manure or grass — as a cheap, environmentally friendly way of slashing its reliance on imported fuels.

The Ministry of Energy has set a target of building 1,540, 100 MW bio-gas plants by 2011, many of them fuelled by solid waste and polluted water.

“We are looking for the most available renewable energy sources and pig manure is abundant,” said Panich Pongpirodom, director-general of the Department of Alternative Energy Development.

Thailand has around 5.8 million pigs and one 100-kg (212-lb) hog produces up to two kg (4.4 lbs) of waste per day.

PIG POWER

For Ong-Arj, biogas was a last-ditch effort to save his 17-year-old hog farm from going under due to falling pork prices and rising costs.

“I was almost ready to give up,” he said. “But after I learned you can use pig waste to make gas, I knew this was a way to pay the bills,” he said.

Ong-Arj looked at a biogas pilot project at Chiang Mai University, but it was too costly.

After cajoling his bankers into a 1.5 million baht loan, he set to work designing his own system.

“Co-generation units cost millions of baht. So I did my own research and modified a car engine myself,” he said, adding his 30,000 baht unit was easier to repair than pricier foreign models.

The pig waste is flushed into a covered 20 meter by 60 meter (66 ft by 196 ft) lagoon, about the size of six tennis courts.

As it decomposes it produces methane — a colorless, odorless gas — which is used to fuel two electric generators that produce 500 kilowatts a day.

That is more than enough to run three pig houses, a feedmill and the family home — saving Ong-Arj about 600,000 baht ($17,543) a year in electricity costs.

“My air conditioning can run all day and all night now,” Ong-Arj said, adding he hoped to sell his excess power to the provincial power grid and lure other farmers to biogas.

Ong-Arj, who also markets pig manure to local growers, is proud that he has found another pig byproduct — electricity.

“In pig farming, the only thing you can’t use is the squeal,” Ong-Arj said.
