This study uses optimization modeling to study efficient ways to integrate renewable energy systems to provide electricity and heat in rural Japan. The model provides minimum cost system configuration and operation taking into account hour-by-hour energy availability and demand. Grid electricity is available to rural areas of Japan, but it is relatively expensive. Local renewable energy generation can be economic while using grid electricity to compensate for the intermittency of the renewable generation.

Global warming increases the acidity levels of oceans

The World Bank (wb) has issued a letter of intent for the purchase of 8 lakh tonnes of carbon credits from the Visakhapatnam-based Institute for Solid Waste Research & Ecological Balance (inswareb).

Proposals for greenhouse-gas reductions have been met with widespread skepticism in the developing world, in part because such countries find their conventional air-pollution problems more pressing. The goal of this article is to examine whether reductions in carbon emissions that are ancillary to conventional pollutant reductions from a policy to phase out small boilers in downtown Taiyuan, China are large enough to make such policies attractive carbon reducing investments to developed countries.
