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.

Clean energy, not coal, is the solution to poverty

It is the development conundrum of our era. Extremely poor people cannot lift themselves out of poverty without access to reliable energy. More than a billion people live without power today, denying them opportunities as wide-ranging as running a business, providing light for their children to study, or even cooking meals with ease.

Ending poverty requires confronting climate change, which affects every nation and every person. The populations least able to adapt – those that are the most poor and vulnerable – will be hardest hit, rolling back decades of development work.

How do we achieve the dual goals of expanding energy production for those without power and drastically reducing emissions from sources such as coal that produce carbon dioxide, the primary contributor to climate change?

There is no single answer and we cannot ask poor communities to forego access to energy because the developed world has already put so much carbon pollution in the air.

An array of policies and programs backed with new technology and new thinking can — if combined with political will and financial support — help poor populations get the energy they need while accelerating a worldwide transition to zero net carbon emissions.

Lighting up the future in Bangladesh

Night falls in Dhaka. Commercial streets glow with lights and the neon-lit stores and restaurants are abuzz with shoppers enjoying a break from Ramadan. This is a great visual spectacle punctuated by the incessant honking of colorful rickshaws.

But the reality is different right outside the capital. Sunset brings life to a halt in rural areas as about 60 percent of rural households do not have access to grid electricity. Kerosene lamps and battery-powered torches are widespread yet limited alternatives, their dim light offering limited options for cooking, reading or doing homework.  

It is a sweltering hot day when our team sets out to visit a household of 14 in the village of Pachua, a two-hour drive from Dhaka. Around 80% of the villagers have benefited from the solar panel systems to access electricity. The Rural Electrification and Renewable Energy Development Project (RERED), supports installation of solar home systems and aims to increase access to clean energy in rural Bangladesh.
 
We’re accompanied by Nazmul Haque Faisal from IDCOL, a government-owned financing institution, which implements the program. “This is the fastest-growing solar home system in the world,” Faisal says enthusiastically, “and with 40,000-50,000 new installations per month, the project is in high demand.”

We’ve now reached our destination and Monjil Mian welcomes us to his house, which he shares with 13 other members of his family, including his brothers, two of them currently away for extended work stints in Saudi Arabia.

Climate finance: The public sector can't do this alone

​We’re doing a lot of talking and listening here at COP 20 in Lima about climate finance – how hundreds of billions of dollars were invested globally last year to clean up the air, get efficient energy to more people, make agriculture more productive, and build resilience to extreme weather events.

We all know and acknowledge much more still needs to be done – the International Energy Agency and others believe we need at least $1 trillion dollars of new investment each year to address climate change.

There’s no way that public money alone can meet that goal. We need to find ways to catalyze the limited public funds we have to unlock private investment. That, of course, means investors need to have the confidence that the right policies are in place to make long-term investments for the climate.

Why Do More Than 50,000 Families in Bangladesh Buy a Solar Home System Every Month?

“Does the solar home system work? Do you really get better lights? Or, is it just a big fuss?’ I have been asking solar home systems households in rural Bangladesh these basic questions for the past five years as part of my implementation review missions for the Rural Electrification and Renewable Energy Development program, which has installed over  2.8 million solar home systems since 2002. This has so far contributed to a 9% increase in access to electricity in Bangladesh.

Three Types of Climate Action for Europe and Central Asia Region

Under current trajectories, the world is headed toward a world that will be 4 degrees warmer by the end of this century. Despite the mounting concern around this scenario, many countries throughout the Europe and Central Asia (ECA) region are understandably reluctant to introduce more ambitious climate policies because they are worried about the negative consequences on competitiveness or energy affordability, for instance.

However, as we try to show in our recent publication, Growing Green: the Economic Benefits of Climate Action, strategic investment in climate action can benefit these countries in the medium- and long-terms – thus offsetting the negative consequences of these investments.

Above all, countries need to focus on three types of climate action: climate action as a co-benefit, climate action as an investment, and climate action as insurance.

IRENA puts renewable energy on the map

With 159 countries—plus the EU— having joined it, a staff of 70 and a $28-million annual budget, IRENA held its third Executive Assembly here, making an impressive show on the sidelines of the summit. One example is its Renewable Energy Roadmap, which attracted lively interest among delegates.

Innovators that could light up Africa

Everyone talks about the crisis of energy access – the 2.7 billion people who use wood and other solid fuels, and the 1.5 billion without access to electricity – but who is doing something about it?

At the African Energy Ministerial Meeting in Johannesburg, South Africa, today, both high-level planning and on-the-ground energy projects were visible, and truly inspiring. In a five hour Green Household Energy Solutions Expo that I had the true pleasure to chair, the Minister of Economic Development for South Africa, Mr. Ebrahim Patel, kicked off the discussion by saying that South Africa was committed to growing nation’s clean energy generation capacity for both domestic use and for export and in the process create green jobs.

The meeting marks a key chance for integration and coordination as the last regional ministerial meeting before the COP17 Climate Conference in Durban, South Africa in December of this year. The room was packed, with over 15 ministers in attendance, and the discussion turned to the benefits of regional integration of transmission systems, building wind, geothermal, and large-scale solar energy projects.

However, the focus and the stars of the meeting were the innovators at the household and local community level who showed the possibilities that exist with a range of new approaches – some technological but many managerial and social as well.

Ron Bills of Envirofit, a producer of high efficiency woodstoves said: “We have sold 300,000 stoves, and can provide high quality stoves to scale up clean energy cooking markets anywhere!” 

The `how-to' of renewable energy

Daniel Kammen's picture

Last month, I blogged about the Special Report on Renewable Energy Sources and Climate Change Mitigation of the Intergovernmental Panel on Climate Change (IPCC), for which I was a coordinating lead author. In that report we found that by 2050, roughly 80 percent of global energy demand could be met by tapping renewable sources. The IPCC’s best-case prediction is contingent on a big caveat, however. It is that government policies must “play a crucial role in accelerating the deployment of Renewable Energy (RE) technologies.”

Fair enough, but which policies work best? Which can be replicated widely? Which sectors need more radical new approaches? Given the complexity of energy technologies, and markets, modes of power generation, transmission, distribution, consumption, metering and billing, and the multiplicity of policies—feed-in tariffs, subsidies, ‘feebates’, renewable portfolio standards, and so on— policy makers are often scrambling for guidance.

As author for the Policy and Deployment chapter of the IPCC report, as well as a member of the Summary for Policymakers’ team, I am pleased to suggest a useful source: a recent Discussion Paper No. 22 produced by my World Bank colleague Gabriela Elizondo Azuela, along with Luiz Augusto Barroso, Design and Performance of Policy Instruments to Promote the Development of Renewable Energy: Emerging Experience in Selected Developing Countries.

Elizondo and Barroso studied grid-connected RE policy options used in six countries—Brazil, India, Indonesia, Nicaragua, Sir Lanka and Turkey. They find that sound governance is an essential condition for the success of policy incentives that aim to accelerate the integration of renewable energy. “For example,” Elizondo says, “legal and regulatory frameworks for grid connection and integration have to be in place before RE policy is introduced.” In the IPCC report we called this the ‘enabling environment’.

80% of all energy could be from renewables by 2050...with the right policies

In just one day, the sun delivers about as much energy as has been consumed by all human beings over the past 35 years. So why haven’t we exploited more than a tiny fraction of this potential? There are many reasons: cost, storage, transmission, distribution, entrenched subsidies and technological challenges are but a few of them.

But the reasons not to take advantage of renewable energy are falling away. A report published this week by the Intergovernmental Panel on Climate Change (IPCC) found that close to 80% of the world’s energy demand could be met by tapping renewable sources by 2050, if backed by the right enabling public policies. I served as a Coordinating Lead Author for the Policy and Deployment chapter of the report, as well as member of the Summary for Policy Maker’s team, and I can attest to how much rigorous analysis and effort comparing data and sources went into this process and document.

The same Special Report on Renewable Energy Sources and Climate Change Mitigation found that the technical potential of renewable energy technologies “exceeds the current global energy demand by a considerable amount—globally and in respect of most regions of the world.”

These encouraging findings were released Monday, May 9, after being studied carefully, examined, and then approved by member countries of the IPCC in Abu Dhabi, United Arab Emirates.
