ing solar power (CSP) and photovoltaics (PVs) – and notes that while these types seek at the maximization of solar energy, they have different approaches (Hamer 1).
The considered questions in the article are related to the primary types of solar energy, the suitability of solar energy in heating water and the benefits that zero net energy constructions give to consumers. In this line, Hamer states that the world’s global energy needs will be largely dependent on the use of solar devices to harness light and heat from the sun for the generation of electricity via photovoltaic cells, owing to the declining prices of solar collectors. This reason is also largely supported by the sunny forecasts put on solar energy and a resemblance of the electricity system to the internet, having no particular center of activity, except for the photovoltaics integrated into roofs and windows.
Consequently, Hamer states that there is an increase in the production, but, a subsequent decline in purchasing costs of PVs; hence, likely to have a significant impact on the installation of PVs and access to electricity. This would then classify solar energy for the many uses that electricity can be put to such as heating of water. PVs are also environmentally friendly as they produce no greenhouse gases or atmospheric emissions as a technology. Therefore, it presents itself as the most likely choice of renewable energy technology for embracing by the public (Hamer 1).
Finally, a proposal for zero net energy buildings is given in which the Department of Energy is considering producing houses that consume no energy on net rate, but, incorporate numerous technologies for future homes, including the solar thermal and photovoltaics.
In this article, the core theme as presented by Haugen is that of the effective production of electricity through solar energy. First, the energy is described as clean and reliable by the National Renewable Energy Laboratory (NREL), as a counter for myths over
