JEROME T. GARDNER COLUMBIA SOUTHERN UNIVERSITY ABSTRACT Since first discovered in the 1860s‚ the concept of storing energy from the sun to use as a source of power has been studied and pursued by many programs. Either using solar collectors or photovoltaic cells‚ the methods of using solar power are becoming more efficient and cost-effective. Solar technology is currently being used by homes and businesses‚ but is still too expensive and risky for many residents. Researchers are still making advances

scientific circles as photovoltaic shingles‚ let you incorporate solar technology right into your roof. Reroofing with these shingles is an excellent way to show some love to the planet and your budget. Let’s take a look at how it all works. The Beginning Once upon a time‚ solar roof panels were cumbersome and expensive. Large arrays had to be bolted onto rooftops or installed in large fields in order to capture enough light to work. In 2005‚ the creation of photovoltaic roof tiles allowed thinner

Geothermal energy What is geothermal energy‚ and how can we use it in society? Geothermal energy is the use of the Earths very own energy. It’s renewable‚ clean and can range to easily acquirable hot springs on the surface or hot rock found a few miles below the surface. Or you can go a bit deeper and hit the extremities of the molten rock (magma). In the US around 80% of all geothermal hotspots are found on the western states i.e. Alaska and Hawaii. Wells are drilled deep into the underground

Definition of a Net-Zero Energy Home A Net-Zero Energy Home (NZEH) is “capable of producing‚ at minimum‚ an annual output of renewable energy that is equal to the total amount of its annual consumed/purchased energy from energy utilities” and emits zero net carbon (1). This concept is becoming increasingly popular as people are becoming more aware of the effects of buildings on the environment. However‚ to build a net-zero home‚ in-depth design considerations to minimize “the energy requirements

dams. Photovoltaics(often abbreviated as PV) is a simple and elegant method of harnessing the sun’s energy. PV devices (solar cells) are unique in that they directly convert the incident solar radiation into electricity‚ with no noise‚ pollution or moving parts‚ making them robust‚ reliable and long lasting. Solar cells are based on the same principles and materials behind the communications and computer revolutions‚ and this CDROM covers the operation‚ use and applications of photovoltaic devices

process for converting sunlight into heat and or electricity. In the case of solar panels‚ photovoltaics are used to convert light directly into electric current. Concentrated solar power can also be used‚ which is the indirect conversion of sunlight into power‚ like during the use of methods such as solar water heating. Solar power plants first came into use in the 1980s. Solar panels are composed of photovoltaic (PV) cells that convert light directly into electric current. Solar cells produce direct

Stand-Alone Hybrid Power Systems (SAHPS) is presented. It consists of two level named Centralized Fuzzy Supervisory Control (CFSC) which choose the power references for each Decentralized Robust Fuzzy Scheduler Control (DRFSC). SAHPS comprises: a photovoltaic panel (PV) and Wind Turbine (WT) as renewable sources‚ a micro turbine generator and a battery storage system. The proposed control strategy is able to satisfy the load requirements based on a fuzzy supervisor controller and manage power flows

received from a field of heliostats onto a central tower. Solar power is the conversion of sunlight into electricity‚ either directly using photovoltaics (PV)‚ or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into electric current using the photoelectric effect.[1] Commercial concentrated solar power plants were first developed in the
