This paper defines the maximum possible vertical extent of hydrothermal circulation in granitic crust, and thus the maximum depth within which geothermal reservoirs can be encountered. To evaluate prospective geothermal fields we constructed a geothermal database in northern Honshu, Japan that...

Recent statistics indicate that in 2005 the world consumed about 0.5 ZJ (ZJ = 10<sup>21 </sup>Joules) of energy. If one assumes that the future world population stabilizes at 10 billions, and the people consume a similar amount of energy per capita to that of the people in the presently developed...

Flooded mine workings have good potential as low-enthalpy geothermal resources, which could be used for heating and cooling purposes, thus making use of the mines long after mining activity itself ceases. It would be useful to estimate the scale of the geothermal potential represented by...

Heat flow and geothermal gradient of the sedimentary succession of the Western Canada Sedimentary Basin (WCSB) are mapped based on a large thermal database. Heat flow in the deep part of the basin varies from 30 mW/m<sup>2</sup> in the south to high 100 mW/m<sup>2</sup> in the north. As permeable strata are required...

Solar air collectors have various applications: on the one hand, they can be used for air heating in cold seasons; on the other hand they can be used in summer to evacuate the warm and polluted air from residential, offices, industrial, and commercial buildings. The paper presents experimental...

China’s emissions continue to rise rapidly in line with its mounting energy consumption, which puts considerable pressure on China to meet its emission reduction commitments. This paper assesses the impacts of CO<sub>2</sub> mitigation measures in China during the period from 2010 to 2050 by using a...

The two major pathways for energy utilization from biomass are conversion to a liquid fuel (<i>i.e.</i>, biofuels) or conversion to electricity (<i>i.e.</i>, biopower). In the United States (US), biomass policy has focused on biofuels. However, this paper will investigate three options for biopower: low...

Bioenergy is a new source of energy that accounts for a substantial portion of the renewable energy production in many countries. The production of bioenergy is expected to increase due to its unique advantages, such as no harmful emissions and abundance. Supply-related problems are the main...
