Answer:Both of the major technologies used to overcome environmental obstacles in Dubai require high investment of energy resources. Dubai's climate is regulated by the technologies of evaporative cooling and air conditioning. Both of these technologies rely on a significant amount of fossil fuels to produce the benefit of a more tolerable climate. Therefore, high energy costs and pollution are two drawbacks associated with these technologies. Dubai meets 90 percent of its freshwater needs through the technology of water desalination. Desalination plants also require significant energy resources to operate, creating both expense and pollution.
