Renewable Energy in Developing Countries - Use of Renewables

Use of Renewables

Many recent trends reflect the importance of developing countries in advancing renewable energy. Collectively, developing countries have more than half of global renewable power capacity. China and India are rapidly expanding markets for renewables. Brazil produces most of the world’s sugar-derived ethanol and has been adding new biomass and wind power plants. Many renewables markets are growing at rapid rates in countries such as Argentina, Costa Rica, Egypt, Indonesia, Kenya, Tanzania, Thailand, Tunisia, and Uruguay.

In isolated rural areas, electricity grid extensions are often not economical. Off‐grid renewable technologies provide a sustainable and cost‐effective alternative to the diesel generators that would be otherwise be deployed in such areas. Renewable technologies can also help to displace other unsustainable energy sources such as kerosene lamps and traditional biomass.

Technology advances are opening up a huge new market for solar power: the approximately 1.3 billion people around the world who don't have access to grid electricity. Even though they are typically very poor, these people have to pay far more for lighting than people in rich countries because they use inefficient kerosene lamps. Solar power costs half as much as lighting with kerosene. An estimated 3 million households get power from small solar PV systems. Kenya is the world leader in the number of solar power systems installed per capita. More than 30,000 very small solar panels, each producing 12 to 30 watts, are sold in Kenya annually.

Micro-hydro systems configured into village-scale or county-scale mini-grids serve many areas. More than 30 million rural households get lighting and cooking from biogas made in household-scale digesters. Biomass cookstoves are used by 40 percent of the world’s population. These stoves are being manufactured in factories and workshops worldwide, and more than 160 million households now use them.
