​Are we harnessing the power of the sun?

Are we harnessing the power of the sun? With the success of rooftop solar and other initiatives, we’re beginning to head in the right direction.

Solar success has come from unexpected quarters. For example, Germany is probably not the first country that comes to mind when you think of sunshine, but we can follow Germany’s lead. It’s the world’s biggest small-scale photo-voltaic user with an installed capacity of 32 gigawatts, and 60 percent of capacity is from solar panels that are installed on people's roofs.

Germany also launched a 100,000 rooftops program, which provided concessional, 10-year loans along with attractive feed-in tariffs to further incentivize households to participate. This was soon after the success of its pilot 1,000 rooftops program, which created the right incentives and targets were achieved a year ahead of schedule – in 2003. 
 
Germany, Japan and the U.S. state of California are fulfilling their strong solar power potential, and we could all learn from their examples – especially nations that haven’t yet explored the proven promise of solar.
 
Statistics like these convince me that there is so much more we can and must do. I’m heartened that progress in India has been steady, with successes that prove the country is ready for more.

A small PPP in Ukraine delivers big results

Most public-private partnership (PPP) transactions you hear about are large, multi-million dollar infrastructure deals with serious global players competing in international tenders.

But PPPs don't have to be big to be successful. In Malyn, a town of nearly 30,000 in Ukraine, a biofuel PPP helped the city administration heat three schools last winter by refitting a municipal boiler house, allowing it to substitute expensive, unreliable imported natural gas with locally-produced biofuel made from locally-produced pellets made from wood or straw.

The struggle for survival for Caribbean cleantech SMEs

They had to do something different, something memorable, which would make people realize just how tough it is for small businesses in the Caribbean to survive, “So we held a funeral”. Rosalea Hamilton, the President of the Jamaica-based MSME Alliance explained that they staged a funeral to mourn for the death of small and medium enterprises (SMEs) in Jamaica. The objective was to draw attention to a petition presented to the Prime Minister on ways to support the sector. As the poster for the event underscored, if nothing changed to help Caribbean entrepreneurs, their ventures were as good as dead.Life isn't a beach for cleantech SMEs in the Caribbean, which face high energy costs, lack of financing and other challenges.

According to Rosalea, one of the top challenges facing businesses in Jamaica is the cripplingly high electricity costs, which can account for 25% of a business’s expenses. Jamaica, along with many other Caribbean countries, is highly dependent on foreign oil. This is in spite of numerous domestic natural resources that could be used to move away from fossil fuels, such as solar, wind, and geothermal energy, biofuels such as bagasse, and waste-to-energy systems. Given the high energy prices, start-ups developing alternative energy solutions should thrive in the Caribbean. But ask regional cleantech entrepreneurs, and a different story emerges.

The next food crisis - is it coming?

Remember the food and fuel crisis that preceded the global economic and financial meltdown? Many in the advanced economies have long forgotten it; people in developing countries have very vivid memories. Are we about to relive the crisis? 

How windy is your neighborhood? Interactive map shows you

Here’s a website that might pique your interest, even if you don’t plan on becoming the next T. Boone Pickens – a wealthy American businessman who is investing millions of his own dollars in wind energy. A site called FirstLook has a Google Maps mashup overlaying years of meteorological wind data onto an interactive map.

They’ve recently expanded their wind data to cover the entire planet, making it a really easy tool to see potential spots for future wind farms in Mongolia (pretty good) versus Indonesia (not so good). The website sells detailed site location information, which is intended for entrepreneurs looking to get in on the ground floor of alternative energy investments. Still, I think the free wind speed data is interesting by itself.

The FirstLook site also has a section to look at an area’s solar satellite data, but it unfortunately only covers the places in the United States.
