Economic growth and environmental sustainability from renewable energy applications

The use of fossil fuel causes severe environmental problem such as climate change in the global scale and acid rain in the regional level. Along with its nonrenewable property, renewable and clean energy sources must be explored so as to keep the economy growing sustainably. Nowadays many renewable energy alternatives such as bioenergy, solar power, hydro power, and wind power have been employed, and each of them has their own pros and cons. This special issue focuses on the use of urban and rural wastes in several aspects such as (i) the use agricultural residuals in bioenergy production; (ii) treatments of municipal solid waste in pyrolysis and biochar application; (iii) sewer sludge and other organic matters in renewable energy production; and (iv) plastic materials in wind farm construction and production of solar panels, to assist the production of renewable energy to improve the resource management and maintain the environment.
