Recognizing this, the government of the United Kingdom has a basic policy aimed at reducing carbon dioxide emissions [Ren21 2008: 30]. Carbon emissions from vehicles and fossil energy are believed to be the primary cause of anthropogenic global warming.
"Renewable energy offers our planet a chance to reduce carbon emission, clean the air, and put our civilization on a more sustainable footing. It also offers countries around the world the chance to improve their energy security and spur economic development."
Mikhani  has shown that we do not need nuclear nor fossil energy to sustain the worlds economies. According to Mikhani [2008: 133], an electricity grid can derive power from solar photovoltaics (as much as 35%), biomass (as much as 25%), wind energy (as much as 15%), and the rest from hydropower and related energy sources. Mikhani  pointed out that renewable sources are cheaper (p. 133).
Hotels and motels spend about $2,196 per room on energy that represents 6% of their operating costs [EPA 2007: 2]. Hotels and motels mainly use energy from electricity and natural gas [EPA 2007: 2]. Utilization of two sources of energy is as follow [EPA 2007: 2]:
Citing the experience of European hotels and motels, Hendrikx [2008: 5] reported that 40% of the energy used by hotels is obtained from electricity. Hendrikx also reported that 31% of hotel/motel energy requirements are used for space heating, 17% for heating tap water, 15% for cooling, 12% for lighting, 5% for cooking, and the rest for miscellaneous use (p. 6). In contrast, however, 45% of electricity is used for lighting alone (p. 6).
Thus, the hotel/motel industry is a potential large-scale user of energy from water. At the same time, the industry can be a beneficiary in the shift to renewable energy so long as renewable energy is cheap as per the claim of Mikhani .
In its latest report available, Ren21 [2008: 6] revealed that, worldwide, electricity
