    Welcome to Renewable Energy Science and Technology      

Energy and environmental issues are among the most important problems of public concern. Renewable Energy Science & Technology (REST) strives to work with you towards a clean environment. We help you to understand and to utilize solar and wind energy, the promising solutions to our environmental issues and energy crisis. 


Annual solar energy at the Earth's surface amounts to about 3.3E+24 joules, more than six thousand times the world's total energy consumption.
Global Energy Consumption in 2006 was 459 quadrillion Btu, or 4.8E+20 joules, equivalent to a power of 15 billion kW (1.5E+10 kW).

Global wind within 200 meters above the surface provides much more power than global power consumption. 
World Electricity Generation totals 4 billion kW (4.0E+9 kW). 

A 50 m2 solar panel situated on a roof in Maryland can produce 12,000 kW hours of electricity annually, capable of satisfying the electricity needs of an average American household. 

Solar energy from just one percent of the land in the United States can meet the whole nation's energy needs!


Two personal automobiles annually consume 1000 gallons of gasoline, or 1.3E+08 kW. 
One turbine with a 20 meter rotor on a 25 meter tall tower can supply enough energy for usage by two cars. 

  Renewable Energy Survey and Prediction

We use National Oceanic and Atmospheric Administration (NOAA) data to calculate solar and wind energy distributions. The Google map-based tool on this website can help you and help policy makers to estimate solar and wind energy. We can use weather forecast data to predict solar and wind energy in order to optimize potential renewable energy production and storage.

Solar Energy

Solar energy is often referred to as solar heat and electricity converted from sun radiation. Solar heat has been used to dry foods, cook materials, and produce hot water. Solar electricity has also become a unique energy resource on spacecrafts. Photovoltaic energy results from the conversion of sunlight into electricity through a photovoltaic (PV) cell, commonly called a solar cell. Solar thermal technologies use concentrator systems to heat a working gas or fluid for running a conventional power plant.

Wind Energy

Wind energy is atmospheric kinetic energy, calculated from an air mass and its wind speed. Wind power is often referred to as electricity converted from kinetic energy. This website provides a tool and a data set for you to estimate wind energy, wind power, and wind power density (wind power for a unit area). You can zoom in/out and select an area. You can choose a rotor diameter for your wind turbine. You can enter the number of wind turbines. You can also put your wind turbine at various altitudes.
