What technologies and solutions can significantly increase the contribution from geothermal sources for heating, cooling and power generation?

Geothermal energy is a sustainable source of both heat and power. While geothermal power is possible only in select regions, it constitutes a baseload power source where available. Geothermal heating (and cooling), usually through heat pumps, is possible in many regions of the world. The challenge for enhancing geothermal's contribution to energy security and sustainability has to do with innovations that can make it less costly, more safe and with fewer environmental impacts.
