UNIT 4 ASSIGNMENT
The Future of Energy: Guiding Decisions with Evidence
Big Ideas in Science: From Methods to Mutation
Professor Molika Chea
Basically, humans use lots of energy for heating, lighting, movement, machines, etc. That energy has to come from an energy source. Some sources are renewable, some sources are non-renewable. Texas energy use per person has fallen in recent years and today is at its lowest level since 1965. Texas per capita residential use of electricity is significantly higher than the national average, however, due to the high demand for air-conditioning during hot summer months and the widespread use of electricity as the primary energy source for home heating during typically mild winter months. Despite large net interstate electricity imports in some areas, the Texas power grid is largely isolated from the integrated power systems serving the eastern and western U.S., and most areas of Texas have little ability to export or import electricity to and from other states. Texas has a great assortment of energy options available to power its future. As the supply of traditional fuels become less certain and more costly, advanced technology will play an increasingly important role. In Texas, solar power is used for a variety of purposes including, powering homes, school crosswalk warning signs and water pumping systems. Texas is ranked first in solar energy potential according to the State Energy Conversation Office (SECO) but is currently only tenth in solar energy production. Homeowners can save energy while improving their home's comfort level by adopting energy-efficient building practices. Substantial savings are possible whether building a new home, renovating an existing one, or simply updating some features to improve your home's
efficiency. At the same time, homeowners can use green power for their home to reduce further their consumption of energy from fossil fuels...
