After being hung up overnight in a breezy location, shirts worn once (even in the tropics!) smell quite fresh enough to wear again.
Washing and drying clothes. Washing and drying clothing are common activities that can use a lot of energy - if we aren't careful. But there are a lot of things, most importantly washing in cold water and line drying, which are not only greener, but will make your clothes last longer (as long as you don't leave them outside too long, to fade).

Why does it matter? - Energy usage: We need to use less energy with efficient washers and cold water (unless there is abundant solar hot water), and use renewable energy where possible.

Water usage: The more water we use, the harder it is to process the waste water, and the more strain we place on the water supply.

Water pollution: Minimize the use of detergent. Consider these words about the chemicals you use. Once people appreciate that they make other things dirty when they make their clothes clean, they think differently about what they're doing.

Jane Goodall, September 2011
There would be very little point in my exhausting myself and other conservationist themselves in trying to protect animals and habitats if we weren't at the same time raising young people to be better stewards.

Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used.

Solar powered electrical generation relies on heat engines and photovoltaics. Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, solar hot water, solar cooking, and high temperature process heat for industrial purposes.To harvest the solar energy, the most common way is to use solar panels.

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.

ENGR 215 Introduction to Design projects – Spring 2010: RCEA: Two labs of the Spring 2010 semester of Engineering 215 worked with the Redwood Coast Energy Authority to build energy education boxes for classrooms in Humboldt County. These boxes are designed for different K-12 grade ranges and cover one of three topics: energy conservation, renewable energy or climate change.

Spring 2010 ENGR 215 Intro to Design Projects - RCEA
