As the price of oil and its derivatives fluctuate and reserves of easily accessible sweet crude decline, the cost of energy consumption has increased. Conversely, world energy consumption increased over 49% between 1984 and 2004 [1]. Based on calculations of extraction costs and energy needs, it is clear that fossil fuels are an unsustainable source of energy and as a result, there has been increasing interest in finding alternative methods of energy generation and reducing current use. This interest has been exacerbated due to the negative environmental impact of burning fossil fuels. Buildings are an enormous part of overall energy ...

In 2012, global private investment in solar power was $142.5 billion dollars for a meager return of $93 billion (Isola, 2013). This is a loss of 35 percent, which is far from profitable. The inability of the solar industry to show a profit reflects its use of inefficient technologies and poor business models. It is simply too early in the technology development to justify pouring large investments into the industry. With the current state of the solar energy industry, the produced energy remains too expensive to compete in the energy market. Until the solar energy industry becomes profitable, decreasing dependency on oil ...
