And here is this week’s Green numbers:

  • Six Infrastructure Projects to Save 1.3 Billion Gallons of Water in Australia

    Australia is no stranger to tight water supplies, and fortunately that means smart water conservation strategies are being devised all the time. Australia is leading the way in everything from strategies to combat desertification to using renewable energy for desalination plants, and now it is putting that knowledge to work on six new infrastructure projects that can save 1.3 billion gallons of water.

  • Girls now begin puberty aged 9

    GROWING numbers of girls are reaching puberty before the age of 10, raising fears of increased sexual activity among a new generation of children.

    Scientists believe the phenomenon could be linked to obesity or exposure to chemicals in the food chain, and is putting girls at greater long-term risk of breast cancer.

    A study has revealed that breast development in a sample of 1,000 girls started at an average age of 9 years and 10 months ? an entire year earlier than when a similar cohort was examined in 1991.

  • Coal-fired power was the big loser in the economic downturn | Grist

    There’s some interesting new data out on recent shifts in electricity demand and consumption, courtesy of the DOE/EIA.

    In 2008, total U.S. power generation was 4.1 million GWh. In 2009, that fell by 4 percent, to 3.9 million. That’s a 4 percent reduction — clearly the result of the economic slowdown. Nothing surprising there.

    What’s interesting, though, is how generation shifted by fuel type. Over the same year, coal-fired power generation fell by 11 percent, from almost 2 million GWh to just under 1.8 million.

  • New Microsoft App Can Cut PC Power Consumption By 80%

    Just how important is turning off computers at the end of the day in an office building? Very, if a company wants to save big bucks on electricity bills. According to UC San Diego researchers, 50-80% of a modern building’s electricity use goes to IT equipment, particularly desktop computers. A report last year showed that not shutting down PCs equated to $2.8 billion in wasted electricity. Still, many offices don’t encourage their employees to hit shut-down on their PCs for a variety of reasons, including updating software while everyone is out or being able to keep the computer attached to the network so information on the machine can be accessed at any time. However, Microsoft’s new Sleep Proxy system claims it can help cut energy consumption by 60-80%, without getting in the way of office systems.

  • RWE npower: wholesale electricity prices ?must double? to meet UK targets

    At a presentation at the Oxford Energy Futures conference on June 11th, Andy Duff, non-executive chair of RWE npower, made some controversial assertions about the future of electricity in the UK. He focused on three propositions.

    a)????? The UK cannot meet its carbon targets without new nuclear

    b)????? Electricity demand will grow at 1% less than GDP growth

    c)?????? The UK will not have enough electricity capacity by the latter part of this decade unless UK society accepts a doubling of wholesale electricity prices, which is the minimum required to free the capital investment required to 1) meet demand and 2) decarbonise sufficiently fast.

    In summary, we need nuclear and we all need to accept a substantial rise in electricity prices to pay for it.

  • 60% of Chinese Consumers Sceptical of Companies’ CSR Communications: Global Poll

    Chinese consumers are becoming as cynical as those in the West about the way companies communicate about their social and environmental performance, according to the latest wave of GlobeScan’s annual global tracking research on public views of corporate social responsibility.\n\nThe study, which interviewed over 30,000 people across 34 countries, finds that while in 2005 more than 80 per cent of Chinese consumers felt that companies communicated ‘honestly and truthfully’ about their social and environmental performance, this has now fallen sharply, with only 40 per cent feeling this way in this year’s study.

  • E-mail from BP engineer called Deepwater Horizon rig a ?nightmare well? six days before explosion

    Today, the chief executives of the five big oil companies ? including BP?s Tony Hayward ? are going to testify before the House Energy and Commerce Committee. According to an e-mail released by that Committee yesterday, a BP drilling engineer warned that the Deepwater Horizon oil rig was a ?nightmare well? that had caused the company problems in the past. The e-mail came just six days before the well exploded:

Is there really any need for baseload power?

No nuclear waste

The electricity grid may not need “baseload” generation sources like coal and nuclear to backup the variability of supply from renewables.

Jon Wellinghof is the Chairman of the US Federal Energy Regulatory Commission (FERC). FERC is an independent agency that amongst other things, regulates the interstate transmission of electricity, natural gas, and oil – for more on FERC’s responsibilities see their About page. Chairman Wellinghoff has been involved in the energy industry for 30 years and appointed to the FERC as a commissioner by then president Bush in 2006.

Last year, shortly after being appointed as Chairman of the FERC, Mr Wellinghoff announced that:

No new nuclear or coal plants may ever be needed in the United States….

Wellinghoff said renewables like wind, solar and biomass will provide enough energy to meet baseload capacity and future energy demands. Nuclear and coal plants are too expensive, he added.

“I think baseload capacity is going to become an anachronism,” he said. “Baseload capacity really used to only mean in an economic dispatch, which you dispatch first, what would be the cheapest thing to do. Well, ultimately wind’s going to be the cheapest thing to do, so you’ll dispatch that first.”…

“What you have to do, is you have to be able to shape it,” he added. “And if you can shape wind and you can effectively get capacity available for you for all your loads.

“So if you can shape your renewables, you don’t need fossil fuel or nuclear plants to run all the time. And, in fact, most plants running all the time in your system are an impediment because they’re very inflexible. You can’t ramp up and ramp down a nuclear plant. And if you have instead the ability to ramp up and ramp down loads in ways that can shape the entire system, then the old concept of baseload becomes an anachronism.”

This was quite an unusual contention at the time (and still is) and despite the Chairman’s many years working in the sector it was, by and large, ignored – even by the administration who had appointed him to the Chairmanship. In fact, the Obama administration has since announced financial backing for new nuclear power plants.

However, a study published last week by the Maryland-based Institute for Energy and Environmental Research backs Chairman Wellinghoff’s assertion. In a study of North Carolina’s electricity needs it concluded backup generation requirements would be modest for a system based largely on solar and wind power, combined with efficiency, hydroelectric power, and other renewable sources like landfill gas:

“Even though the wind does not blow nor the sun shine all the time, careful management, readily available storage and other renewable sources, can produce nearly all the electricity North Carolinians consume,” explained Dr. John Blackburn, the study’s author. Dr. Blackburn is Professor Emeritus of Economics and former Chancellor at Duke University.

“Critics of renewable power point out that solar and wind sources are intermittent,” Dr. Blackburn continued. “The truth is that solar and wind are complementary in North Carolina. Wind speeds are usually higher at night than in the daytime. They also blow faster in winter than summer. Solar generation, on the other hand, takes place in the daytime. Sunlight is only half as strong in winter as in summertime. Drawing wind power from different areas — the coast, mountains, the sounds or the ocean — reduces variations in generation. Using wind and solar in tandem is even more reliable. Together, they can generate three-fourths of the state’s electricity. When hydroelectric and other renewable sources are added, the gap to be filled is surprisingly small. Only six percent of North Carolina’s electricity would have to come from conventional power plants or from other systems.”

With larger and more inter-connected electricity grids, the requirement for baseload falls even further because the greater the geographical spread of your grid, the greater the chances that the wind will be blowing or the sun shining in some parts of it.

So, is there really any need for baseload power any more, or is this now just a myth perpetuated by those with vested interests?

Do risk and compliance have a part to play in reducing pollution?

by

Do risk and compliance have a part to play in reducing pollution? EQ2 certainly thinks so.

Steve Burt, the founder and CEO of EQ2, is a former economist having worked at senior levels with Dun & Bradstreet and British Petroleum. His approach, which he calls Granular Resource Economics (GRE), enables companies to quickly see at a glance the entire spectrum of their emissions down to parts per million.

Why is this important?

Well, consider one of the verticals Steve is looking at – the aviation industry (see EQ2‘s excellent Sustainable Flying Report – PDF) . As Steve says, a single flight taking off from an airport, in pollution terms, is not a significant event. But when an airport handles hundreds of flights per day. What is the accumulated pollution from all the flights, incoming and outgoing, it has ever handled? Now project this forward for all the flights it is going to handle…

When you think of pollution from planes, you typically think in terms of CO2. EQ2 go well beyond that though and in the case of aviation, for example, you will also see the numbers for SOx, NOx, and other constituents emitted from jet fuel such as mercury, selenium, arsenic, particulates, etc. When you start to run those numbers for even moderately sized airports, the results can be quite sobering. For airports located near water this could be especially troubling.

And it is not just airports – all organisations need to find out what their liabilities are with respect to their accumulated emissions. A recent report for the UN has found that the world’s top firms caused US$2.2 trillion of environmental damage in 2008 alone. This is obviously unsustainable and is merely a preface to more restrictive pollution controls being enacted which:

is likely to argue for abolition of billions of dollars of subsidies to harmful industries like agriculture, energy and transport, tougher regulations and more taxes on companies that cause the damage

Imagine for a sec if communities in the vicinity of Drax or Kingsnorth coal-fired power plants in the UK decided to sue for the environmental damage wrought on them by these power plants. The kind of information EQ2 can provide would be invaluable in helping these facilities reduce their emissions and minimise the increasing risks associated with being a polluter.

With that in mind, how many firms can afford to remain ignorant of the full spectrum of their emissions?

Seriously people, the correct order is planet first, then people, then profit.

Someone I know and respect made a bit of a boo boo last week and I called him on it. In response to the announcement of BP’s “Giant oil find” in the Gulf of Mexico, he Tweeted:

Giant oil reserver [sic] in the Gulf, most rushing to drill it except the US. Wouldn’t that be ready made jobs and revenue?

To which I replied:

Wouldn’t it be ready-made pollution (CO2)? Ethics of celebrating jobs & revenue based on planetary destruction?

People seem to be all too ready to forget about the fact that climate change doesn’t stop to consider whether there is a recession. It doesn’t say, “oh, there’s a down-turn and you want to pump a few extra million tonnes of CO2 into the atmosphere? No problem, you should have said, go right ahead”

At least in the case of the BP find, according to this Wall Street Journal analysis, recovery rates may be as low as 5-15% (150-450m barrels of oil) – still a lot of CO2 but significantly less oil than the headlines were suggesting.

e.on UK, is the energy company which owns the infamous Kingsnorth power station. Kingsnorth is one of the largest coal-fired power plants in the UK and alone is responsible for roughly 7.3m tonnes of CO2 being emitted into the atmosphere per annum. e.on UK has launched Talking Energy, a channel on YouTube to foster an online dialogue about energy.

However, as you would expect, the company stresses energy sources which will benefit e.on and its shareholders in the short-term, as opposed to trying to benefit the planet (and thus the company and its shareholders) in the long term. In the video above you see Jeremy Nicholson, lobbyist and Director of the Intensive Energy Users Group – “a single-issue lobby group which campaigns for secure industrial energy supplies at internationally competitive prices”. Jeremy throws out the old lie about the need for baseload power for the electricity grid as a reason to keep investing in carbon polluting energy sources.

The baseload argument is an old one and one which was given its severest kicking recently when the Jon Wellinghof, Chairman of the US Federal Energy Regulatory Commission said back in April that:

renewables like wind, solar and biomass will provide enough energy to meet baseload capacity and future energy demands. Nuclear and coal plants are too expensive, he added.

“I think baseload capacity is going to become an anachronism,” he said. “Baseload capacity really used to only mean in an economic dispatch, which you dispatch first, what would be the cheapest thing to do. Well, ultimately wind’s going to be the cheapest thing to do, so you’ll dispatch that first.”

Now if the chairman of the US Federal Energy Regulatory Commission believes that renewables can provide enough power to meet baseload and future energy demands, I’m going to take his word over e.on’s and their lobbyist’s.

e.on, some questions for you:

  • Does CO2 cause climate change (and the consequent deaths of thousands of people annually, not to mention species extinctions, environmental destruction, etc.)?
  • Do you care that your pollution is killing people and destroying the planet?
  • When do you plan to stop killing people, destroying the environment and driving species to extinction (i.e. when do you plan to stop emitting CO2)?

Seriously people, the correct order is planet first, then people, then profit.
