Study Notes
Introduction to Solar Energy
- Solar energy is used to power the Sojourner rover on Mars, which was part of the Pathfinder spacecraft mission in 1997.
- The rover's solar panel-generated power allowed it to move around and examine rocks on the planet's surface.
Perceptions of Solar Energy
- Some people see solar energy as a technology for the future, while others see it as something already available and useful today.
- The perception of solar energy can vary depending on individual perspectives and psychological make-up.
History of Solar Energy
- Solar energy has been used for hundreds of years to make people's lives more comfortable, including for heating and weapons.
- The first solar water heating collector was built in the 18th century by a Swiss scientist, which reached a temperature of 190 degrees Fahrenheit.
Current State of Solar Energy
- Solar energy is already being used today in homes, businesses, and industries, and will play an important role in future energy needs.
- The sun provides enough energy to meet the world's energy needs for a full year every day.
Applications of Solar Energy
- Solar energy is used in a variety of products, including solar-powered calculators, watches, and lanterns.
- Millions of people around the world use solar energy as their only available and reliable power source for basic needs like lighting and water pumping.
- Solar energy is used in conjunction with traditional ways of life to become an integral part of people's lives.
Future of Solar Energy
- The house of the future could be a zero-energy house that uses solar panels for power generation and solar collectors for water and space heating.
- Some type of energy will be needed to power the future, and solar energy could be a viable option.
- The answer to the future's energy needs should be obvious: the sun has been a constant source of energy all along.
Discussion Questions
- Why do you think solar energy is not used more today?
- Should governments adopt measures to use more solar energy in the future, or rely on fossil fuels as long as they are available?
- What are some of the economic, social, and environmental issues involved in the use of solar energy?
