  • Generating thermal energy from the Sun – Case Study

    With the rising cost of electricity from fossil fuels, solar thermal energy (STE) currently leads the way as the most cost-effective solar technology. Major solar thermal power industry players are striving to make the economics of solar power a mainstream renewable energy source. Solar thermal electric energy generation concentrates the light from the sun to create heat, and that heat is used ...

  • Solar Heating Reduces Energy Costs at Gaylord - Case Study

    Gaylord Hospital’s quiet 500-acre setting had its drawbacks. There were no natural gas pipelines leading to the area, and installing them would be cost-prohibitive. Instead, Gaylord relied on oil heat, an almostequally daunting expense, especially in Connecticut winters. But then Mark Veere, facility manager for Gaylord, came up with an idea for cheaper energy without digging up those ...

  • What can you achieve with a solar system and battery?

    People often ask us about energy self-sufficiency. Just how hard is it to get to that point where you no longer have to pay a large corporation each time you turn on the kettle? This will depend on your usage patterns but for most people, a mix of renewable systems is the best option. We’ve taken a look at Gabriel’s home renewable systems as an example. Perhaps unsurprisingly, Gabriel ...

  • India’s Potential in Harnessing the Alternate Energy Sources

    Long queues for gasoline, high prices and shortage of gasoline are the signs which show that how natural resources are on the verge of depletion. This shows that it is high time for us to view how to utilize natural resources. India is mainly depended on import of petroleum products for its energy requirements. It meets its requirements by importing 70% of petroleum products. This is a point of ...

  • Welcome to Net-Zero

    For most people (and for most homes) the likelihood of going through a whole year spending next to nothing on energy is a goal that seems far out of reach. In fact, it is only relatively recently that insulation technologies, coupled with cutting-edge renewable energy tools, have made the concept of a net-zero energy use home anything more than a pipe dream. However, thanks to a program at the ...

  • Sustainable development with renewable energy resources: a review

    The most visible effects of the sustainable development movement are found in several global issues such as the greenhouse effect, stratospheric ozone depletion, and loss of biodiversity. Combustion of fossil fuels and global warming are closely associated with each other. There is an urgent need to replace fossil fuels to renewable energy sources. Renewable energy is one of the few means by ...

  • Significance of design for energy conservation in buildings: building envelope components

    Energy efficient buildings consist of using innovative technologies based on renewable energies and a good thermal insulation. Most strategies applied in design and many of the services offered by lodging establishments require the consumption of substantial quantities of energy, water and non–durable products. In most developing countries, it makes perfect sense to focus on the ...

  • Energy and exergy analysis of a solar–assisted heat pump space heating system for clear days

    The studies over solar–assisted heat pump systems have been performed mostly on time periods when solar radiation is high. Therefore, this study focuses on performance analysis of a solar–assisted heat pump system which stores the energy during the clear day and uses it as a heat source of heat pump space heating system during the night. Energy and exergy analyses divided into two parts, which ...

  • Investigation of a hybrid solar and geothermal driven absorption cooling system for district applications

    In this paper, a new hybrid geothermal and solar driven absorption cooling system (ACS) is proposed for low–temperature district energy applications. Two approaches are proposed in this study, namely: a) a new model for determining the specific entropy values of LiBr–water solution and (b) two new energetic and exergetic parameters, namely geothermal contribution index and solar contribution ...

  • Harnessing the Sun`s Energy for Water and Space Heating

    The pace of solar energy development is accelerating as the installation of rooftop solar water heaters takes off. Unlike solar photovoltaic (PV) panels that convert solar radiation into electricity, these "solar thermal collectors" use the sun's energy to heat water, space, or both. China had an estimated 168 million square meters (1.8 billion square feet) of rooftop solar thermal collectors ...
