Cost Per Lumen – The LED revolution

By | | No Comments

Sometimes we get things a little bit right. And all too often we don’t celebrate these little wins. Here is a graph that details how LED light technology has changed our world as cost per lumen. It’s by no means a complete win but with energy requirements cut by up to 80% and our lights burning just as bright, it’s a great little reminder what can be done.

The Great Acceleration

By | | No Comments

In one lifetime humanity has become…

Global Force

Here is one of the scariest slide decks I’ve seen – Using 24 key social, economic, and environmental indicators, Pharand-Deschênes has created a dashboard that shows how human pressure on planet Earth is reaching critical level. Fast. The acceleration shown over the last 60 years is absolutely crazy. Zoom in. Freak out.

These Fossil Fuels Must Be Left In The Ground

By | | No Comments

The Guardian recently covered the difficult question of what fossil fuels MUST be left in the ground to keep global temp rises below 2 degrees. It’s definitely worth a read.

To stay below 2 degrees - between 2011 and 2050 we need to limit emissions to around 1,100 gigatonnes of carbon dioxide (Gt CO2). We’re currently way off. Also keep in mind that the source report from Nature suggests that success is only around a 50% probability, which is a bit of a shocker.

Carbon Tracker released their report last year, as have others over the years, and many media outlets have run stories on the subject, but this new report actually details the facts and figures. Obviously the geopolitical and economic implications are huge.

The graphic below outlines the key items.

The Basics Of Climate Science

By | | No Comments

It doesn’t get much simpler than this. 

In this video The Royal Society and the US National Academy of Sciences explain climate science in 60 seconds.

The Royal Society is a self-governing Fellowship of many of the world’s most distinguished scientists drawn from all areas of science, engineering, and medicine.

“Climate change is one of the defining issues of our time. It is now more certain than ever, based on many lines of evidence, that humans are changing Earth’s climate. The atmosphere and oceans have warmed, accompanied by sea-level rise, a strong decline in Arctic sea ice, and other climate-related changes.”

Why I love Tesla

By | | No Comments

TeslaLast week I was lucky enough to drive a Tesla – What an experience!

Thanks to Laura Cremer who organised the event for the Interface Sustainability Ambassador Training participants.

The entire driving experience was amazing: immediate torque, no noise, huge computer display. I hope one day I’m fortunate enough to own one.

The company is not just interesting for being a pioneer in electric cars, or for making electric cars sexy (now the mainstream German manufacturers are trying to copy it).

What IS interesting from Tesla is now that that job is done, and electric is on its way to becoming mainstream, they are betting big on batteries.

Tesla DashBattery technology is the bottleneck for this industry, it’s also where a lot of the cost is sunk. Owning the supply chain in batteries is a huge bet that could go horribly wrong or could become a pseudo monopoly of the most critical part of the cars of our future.

… keeping in mind we’re not only talking about batteries for vehicles – batteries are also the bottleneck for the domestic PV generation, as well as many other sectors.

However. If anyone can pull it off, Tesla can.

How Solar Will Light The Way in the UK [Study]

By | | No Comments

GS1 Solar ReportGerman think-tank Thema1 has published a report where they outline the solar situation in the UK.

Here are some key extracts – to download the full report click on the image.

In 2015, solar PV globally will overtake both gas and coal to become the number one power generation technology in terms of annual installations.

* We investigate three markets in solar power: large- scale, ground-mounted “solar farms”; commercial roof-top; and residential rooftop. We estimate that all three will be economic without support in the next decade.

*  Increasing cost-competitiveness and capacity growth of solar PV in Britain will impact the British power system, including falls in wholesale power prices, as already seen in Germany. The growth of solar power may threaten electric utilities which fail to transition away from solely supplying electricity, to providing residential energy services.

* We find that unsubsidised residential solar power may be cheaper with battery storage. Unsupported domestic solar battery packs achieve payback periods of little more than 10 years by 2020. By 2025, solar battery packs are fully competitive without subsidies across Britain. That could create an inflexion point driving adoption of domestic solar system.

INCREASINGLY AFFORDABLE - Solar costs have fallen faster than rival technologies. Such cost reductions will continue, leading to ever greater grid penetration in the near and medium term.

LOWER WHOLESALE POWER PRICES - Assuming solar PV continues to have priority grid access, higher installed capacity will lead to falls in wholesale power prices, as seen in Germany

FAST TO BUILDSolar PV has the fastest installation rate in Britain among electricity generating technologies. It takes an average of 1.1 years to generate its first electricity from initial planning application, compared with 5.4 years for offshore wind. EDF Energy has forecast 12 years (from planning application in 2011) to commission the Hinkley Point C nuclear power plant in Britain.

PREDICTABLE - Solar power is variable, but reliable and predictable; day ahead forecasts are about 90% accurate.

SECURE - By relying on a web of thousands or millions of individual installations, solar power can become an important part of a highly resilient and intelligent power network.

CLEAN - Solar power emits next to zero carbon emissions, and also displaces particulate matter (PM) from coal combustion, which is harmful to human health.

An Economy That Works

By | | No Comments

An Economy That Works LogoUK business coalition backs “better growth” roadmap to get economy working harder for the environment and society.

A coalition of some of the UK’s biggest businesses today backed a new macro-economic roadmap for Britain and launched a new independent campaign called “An Economy That Works” based on the findings of a major report.

Campaign founders the Aldersgate Group and its progressive alliance of NGOs and UK businesses argue in their first report that the UK economy risks becoming detached from the long-term needs of society. It says that GDP growth is an important tool in creating prosperous societies, but warns that on its own growth is unable to define a path to lasting prosperity and competitiveness. It says an economy that works for the UK is one that will be low carbon, will deliver high employment and equality of opportunity, and place wellbeing and regard for natural resources at its core.

Sir Ian Cheshire, Group Chief Executive, Kingfisher plc said: “The last seven years have shown us that we urgently need an economy that contributes to society and strengthens it. GDP is not a comprehensive measure of prosperity: it is an important tool, not a goal in itself. Instead of maximum linear growth in GDP, we need to start thinking of maximum wellbeing for minimum planetary input.”

Launching the new campaign, Sir Richard Lambert, former Financial Times editor and former Director-General of the CBI said: ”Single-issue policymaking is struggling to address the complex social and environmental challenges of our time.  The Economy that Works coalition has a relentlessly positive vision and its systemic blueprint for creating decent jobs, delivering equal opportunity, and enhancing wellbeing across the UK is exciting and galvanising.”

Peter Young, Chair of the Aldersgate Group said: “Despite encouraging UK growth figures, we risk getting stuck with reduced wellbeing, rising inequality, continued loss of natural capital and rising resource pressures. Policymakers urgently need to look beyond GDP to define successful growth – setting far more coherent policy goals which strengthen the links between our economy, our society and the environment.”

Oliver Dudok van Heel, Director of “An Economy That Works” said: “Our coalition wants to see an economy that works harder for our society and our environment. Many of our member companies are championing best practice and progressive social and environmental policies that will keep our economy in the fast lane. This campaign is an ambitious attempt to draw these strands together into a joined-up roadmap for policymakers that will help insulate UK society from future economic shocks.”

The organisations behind the campaign – including Aviva Investors, BT, Friends of the Earth, Interface, Kingfisher, M&S, National Grid, Nestlé, RSPB, Sky, the TUC and WWF – hope to spark informed political debate about what UK citizens and businesses want from their economy and inspire policymakers to develop solutions that will keep the UK prosperous, competitive and sustainable for generations to come. Many of them have long been at the forefront of driving progressive ethical and sustainable business practices.

The growing coalition behind the new campaign will work with the UK government over the coming years to identify the key policy levers for change, support their adoption, and encourage wider uptake of innovative business practices that together are needed to guarantee a competitive and successful UK economy now and in the future.

Moving beyond ‘growth’ and defining six core characteristics of ‘An Economy that Works’:

1. High employment 
- investment in job generation and skills development, promoting flexible and part-time working, investing in lifetime educational support to increase financial independence and create fulfilling work opportunities.

2. Equality of opportunity – unlocking a ‘double dividend’: reducing inequality and boosting social and economic mobility for all; cutting the cost of employment and introducing living wage levels.

3. Wellbeing at the core
 - ensuring everyone has confidence their material needs will be met, supported by strong healthcare & education systems, strong social networks & democratic institutions.

4. Low carbon 
- there is no such thing as a high carbon low cost future; effective carbon pricing and policy support for innovation and deployment of low carbon technologies are essential. The environmental goods and services sector is growing and already represents £122bn (9.3 per cent) of the UK economy.

5. Zero waste
 – promotion of a circular economy to cut landfill and promote re-use of materials; UK could cut its reliance on raw materials by 20 per cent by 2020 and unlock a £5.6bn opportunity in UK re-manufacturing.

6. Enhancing nature - The UK’s diverse natural capital provides the economy and society with food, clean air, wildlife, energy, wood, recreation and protection from hazards. Measuring this value to the UK economy and preventing its exploitation makes sound business sense.
