Film is a powerful tool for explaining environmental issues. I first learnt this lesson while trying to enlist local communities in northern Vietnam to help protect a strange blue faced and critically endangered primate called the Tonkin Snub Nosed Monkey. After a morning spent bombarding local leaders with facts and figures, they were polite but unmoved.
Concentrated solar power (CSP) systems are a great promise for renewable energy at scale. But they can use a lot of water, which is a problem since they tend to be located in places where water is scarce. Some concentrated solar technologies need to withdraw as much as 3,500 liters per Megawatt hour (MWh) generated.
Next week, I will be joining World Bank Group President Jim Yong Kim and UN Secretary-General Ban Ki-moon on an historic joint visit to Africa's Great Lakes Region. The aim of the trip is to brainstorm with African leaders solutions to helping the people of the Great Lakes prosper.
This visit is important for two reasons - it highlights a new era of global institutions working together to promote stability, and it signals to the citizens of fragile and conflict affected nations our commitment: we will not leave you behind.
Many countries in today’s world have struggled, or are struggling, through war or political conflict to rebuild themselves and lift their people out of poverty. They are called fragile states, nations with poor health and education, little or no electricity, disorganized or weakened institutions, and in many cases no functioning governments. In Africa, 18 of the 48 countries in the sub Region are considered fragile, six of them so much so that UN, NATO or African Union forces are on the ground helping to keep peace.

Scientists monitoring atmospheric concentrations of CO2 from a mountaintop in Hawaii recently reported that the presence of this greenhouse gas exceeded 400 parts per million (ppm) for the first time in at least three million years – a period when temperatures were much warmer than today. The significance of this seemingly dry statistical trend is stunning as reported in the New York Times:
From studying air bubbles trapped in Antarctic ice, scientists know that going back 800,000 years, the carbon dioxide level oscillated in a tight band, from about 180 parts per million in the depths of ice ages to about 280 during the warm periods between. The evidence shows that global temperatures and CO2 levels are tightly linked.
In addition to the location in Hawaii, several other Global Atmosphere Watch stations from the Arctic to the Equator reported CO2 concentrations exceeding 400ppm.
Experts believe that in order to limit warming to 2°C – a goal based on expected impacts – concentrations should rise to no more than 450 ppm, a level we may reach in only about 25 years based on current trends.

In downtown Houston last month, flags were unfurled everywhere promoting LNG 17 - the biggest global gathering devoted to LNG, or liquefied natural gas, as well as its whole value chain. Bringing together industry, governments and experts on everything from "peak shaving" to floating liquefied natural gas facilities – to how LNG contributes to energy security, the conference proved a good platform to raise up and coming issues. To that end, a World Bank Group session at the conference reviewed our own gas activities, and featured a discussion on "Petroleum Contract Transparency - the new normal?"

Last month, China was granted US$95 million to reduce its production of hydro-chlorofluorocarbons (HCFCs), substances that are used primarily for cooling, refrigeration, and the manufacture of foam products. The funding comes from the Multilateral Fund (MLF) of the Montreal Protocol, because HCFCs deplete the ozone layer and are controlled under the Protocol. With access to these funds, between now and 2015 China will reduce its production of HCFCs by 10%, or 47,000 metric tons from 2010 levels, allowing it to meet the first reduction targets set by the Protocol.
This alone is worth celebrating because China is the world's largest producer of HCFCs. Nearly 50% of its production is consumed by other developing countries, all of whom also face HCFC consumption reduction targets under the Protocol. Herein lies one secret to the Protocol’s success: its ability to regulate both production and consumption worldwide simultaneously, putting into practice an economist’s dream to tackle both supply and demand in tandem. By addressing the supply side of the problem through support to China’s production phase-out, the demand side - in China and in developing countries around the world - can build a sustainable HCFC consumption phase-out response. The ozone layer, and human and environmental health, will all be the better for it.
Last week, the Scripps Institution of Oceanography released data showing that CO2 atmospheric levels had briefly passed 400 parts per million (ppm) and were close to surpassing that level for sustained periods of time. This is bad news. At 450 ppm, scientists anticipate the world will be 2 degrees Celsius warmer than pre-industrial times, and world leaders have agreed that’s a point of dangerous consequences.
Along with this grim news came important new research findings from Professor V. Ramanathan of the Scripps Institution at the University of California, San Diego, and other researchers regarding short-lived climate pollutants – black carbon, methane tropospheric ozone and some hydrofluorocarbons (HFCs). While we continue – and must continue – to hammer away at reducing CO2 emissions, their work supports the argument that also reducing these short-lived climate pollutants (SLCPs) can have an immediate effect on slowing warming and the resulting sea-level rise.

A helpful way for young math students to grasp the concept of exponential growth is to look at water lilies growing on a pond. They grow exponentially and double in area each day. If they will fully cover the pond by the 30th day, on what day is the lake half covered? The twenty-ninth day.
This year I had the honor of teaching 4th year energy systems students who will graduate later this month (their blogs on energy issues will be presented on this site over the summer). These graduates are particularly essential. During their careers they will be part of the world’s largest ever city-building spree. Their task will be to again double the world’s cities.
Coal has been a mainstay of Indian energy. It accounts for 63% of India’s energy consumption, and demand is set to grow dramatically over the coming decades. Coal use for electricity generation is projected to grow 2% every year, almost doubling its share of India’s generating capacity by 2030. According to the International Energy Agency, India is likely to become the second-largest consumer of coal, surpassing the United States in the next five years.
Because coal is both cheap and abundant domestically, it may seem like the perfect solution to India’s energy and electricity woes. However, using coal comes with severe health, environmental, and economic effects. As quality of life improves for most Indians on one hand from economic progress, many could be subject to the vagaries of this dirty pollutant. Also, as the world moves closer to a consensus on climate change, using coal at this growing rate may become untenable.
Two recent studies shed light on the huge environmental damage that is done by coal-fired power plants in India. Professor Maureen Cropper and her co-authors at the University of Maryland estimated premature cardiopulmonary deaths associated with air emissions from 89 power plants from all over India. Last week, Professor Cropper presented their analysis in a World Bank seminar. Their study attributes on average 650 deaths per plant per year to directly emitted sulfur dioxide, nitrogen oxide and particulate emissions from coal plants.
Another recent study published by Greenpeace and authored by Sarath Guttikunda and Puja Jawahar presents more dramatic results than the Cropper study. It suggests that in 2011-2012, emissions from Indian coal plants resulted in 80,000 to 115,000 premature deaths and more than 20 million asthma cases from exposure to particulate pollution with an associated cost of $3.3 billion to $4.6 billion.
