Five Steps to Scale-Up Energy Efficiency

Most experts agree that energy efficiency is a critical building block for sustainable development. This is because improvements in energy efficiency strengthen a country’s energy security, increase competitiveness, ease shortages in energy supply, and lower environmental impacts including local and greenhouse gas emissions.

Why doesn’t it happen then? 

Energy Efficiency: Scaling Up to Cut Costs And Emissions

Energy Efficiency
Energy is essential to heat homes and cook meals. It is needed to deliver proper health care in hospitals and to teach children. It is essential for economic growth and development and for powering industries, farms and businesses. It is at the heart of any effort to make a better life possible for people all over the world, in particular for the world’s poorest.

How Fit Are Feed-In Tariff Policies?

World Bank study of Eastern Europe and Central Asian experience finds that complementary policies needed to get more renewable bang out of FiT buck.

Given that the effects of energy efficiency measures tend to be offset by a greater energy consumption that comes with economic growth, these measures, while important,  will not by themselves be sufficient to achieve major reductions in emissions – making the move toward cleaner energy a rising priority for climate change mitigation.

Why Saving Energy is So Hard

When most people think about energy, they see big power plants and smokestacks. What people generally do not consider is that it is much cheaper and more environmentally friendly to cut energy use than it is to build new power plants.  

The problem is that saving energy is not simple. It requires changing deep-rooted behavior.

PP + EE = An Emerging Driver for Green Growth

Public Procurement.  Energy Efficiency. These are not terms that one normally sees together.  And honestly, neither is a subject likely to keep many people awake at night. But taken together, they can be a powerful force for energy security, greenhouse gas mitigation, and low carbon development.

The logic is simple. Governments on average account for 2-5 percent of national energy use, and this can rise to 20-30 percent in countries with high heating demand or low electrification rates. Between 12 and 20 percent of a country’s gross domestic product passes through public procurement systems.  On both the energy and the procurement sides, government actions matter, influencing private sector purchasing and individual decision-making. Technical specifications used by governments also send signals to suppliers about the types of goods and services that will be in demand, which in turn can influence the products they produce.

Belo Horizonte, no Brasil, busca melhorar a eficiência energética

Belo Horizonte City Skyline

Belo Horizonte está decidida a ser conhecida por seu compromisso com a sustentabilidade. Nos últimos anos, a iluminação pública foi trocada por um sistema mais eficiente, conduziu-se um inventário de emissão de gases causadores de efeito estufa e foram criados programas de compras públicas e construções sustentáveis. A empresa responsável pelo serviço de limpeza pública e tratamento de resíduos gera eletricidade a partir do biogás gerado no aterro sanitário. A cidade se orgulha de seus parques públicos e de sua área verde – com tamanho duas vezes maior que o recomendado pela Organização Mundial de Saúde (OMS).

Brazil’s “Beautiful Horizon” Looks to City-Wide Improvements in Energy Efficiency

The city of Belo Horizonte, Brazil, is determined to be known for its commitment to sustainability.  In recent years, the municipal government has switched public lighting to a more efficient system, conducted a greenhouse gas inventory, and created programs for sustainable public purchasing and building certification.   The utility responsible for public cleaning services and waste treatment generates electricity using biogas from landfills.  The city prides itself on its public parks and on having twice the green area inside the municipal boundaries than is recommended by WHO guidelines. The name of the city itself means “Beautiful Horizon”. Read this post in Portuguese (Leia este post em português.)

Managing Oil Price Volatility: Bringing Latin America’s Lessons to the Pacific

Pacific IslandsIt is well understood that climate change poses specific dangers for small island developing states. Less commented on is another threat: the vulnerability of these states to the repercussions of energy insecurity.  

Pacific islands are some of the most vulnerable.  Spread out over a huge expanse of ocean, pooling power among countries is not the option that it is for other regions.  Lacking fossil fuel resources, many of these states are forced to import oil products over long distances.  When prices spike, these countries are among the hardest hit.  

Global oil prices have now been volatile for ten years, compared with historical trends, with sharp volatility characterizing the markets since late 2007.  During this period, the World Bank has been engaged with developing countries to help them manage and mitigate this volatility so that it does not hamper the development or extension of energy services to poor communities.
