Abstract
The move towards a de-carbonised world, driven partly by climate science and partly by the businessopportunities it offers, will need the promotion of environmentally friendly alternatives, if an acceptablestabilisation level of atmospheric carbon dioxide is to be achieved. This requires the harnessing and use of natural resources that produce no air pollution or greenhouse gases and provides comfortable coexistence of human, livestock, and plants. This article presents a comprehensive review of energy sources, and the development of sustainable technologies to explore these energy sources. It also includes potential renewable energy technologies, efficient energy systems, energy savings techniques and other mitigation measures necessary to reduce climate changes. The article concludes with the technical status of the ground source heat pumps (GSHP) technologies.
Key words: Climate, energy, natural resources, carbon dioxide, technologies.
