Waste-to-energy has recently garnered attention in a number of countries, such as India, Indonesia, and Thailand, as a means to increase supply, offset reliance on other resources, and reduce the growing burden of dealing with waste. Modern biomass was only surpassed by hydro in the mid-2000s, while other forms, particularly solar and wind, have been gaining traction recently (figure 4.3). Large increases in hydropower underpin this trend, though the shares of wind and solar are also increasing. When examining national shares of renewables, it can be noted that countries consuming higher shares of modern renewable energy tend to be hydro-rich (figure 4.5).
