In the first week of Dave's Conservation Challenge, students learn about different types of lighting and take part in a lighting challenge to save energy.
Artificial light uses energy, so we can save energy by choosing natural light if possible and by turning off lights and understanding what types of lighting use the least amount of energy. By saving energy we help to protect our environment and save money in our homes. These are three types of artificial light we commonly use in our homes:
This is the oldest technology and the least energy efficient. We can save energy in our homes if when replacing light bulbs we choose a more energy efficient option.
CFL compact fluorescent lighting
In the mid 1980’s CFLs were introduced to the retail market but although they saved energy compared to incandescent lighting they were expensive so market uptake was slow. Nowadays CFLs are an affordable energy saving option to incandescent lighting.
LEDs are the most efficient and newest lighting technology. Ranging from street lighting, to holiday lights to lights in our homes, LEDs are being used more and more. This lighting has a longer lifetime and uses 75% less energy than other lighting (incandescent and fluorescent lighting). There is also a range of daylight LED bulbs, which provide an alternate to natural light if that is not accessible. Go to bchydro.com for information on LED lighting.
Using natural light helps us save energy as we can turn off artificial lighting but the following are also benefits to our health:
Tips to increase natural light and conserve energy
A greater understanding of energy-efficient lighting empowers students to practice energy conservation and care for their near environment. With your help, we can foster a culture of Power Smart youth in British Columbia together.
We use energy in our daily lives in many ways. We use it to get to school, power our lights, cook our food, heat our homes and to make and transport goods. Some of our energy comes from clean renewable sources like the sun, wind and water. Fossil fuels (coal, oil and natural gas) are also used as energy sources. They come from ancient plants and animals, and when burned, release greenhouse gases into the atmosphere. Greenhouse gases, including carbon dioxide, methane, nitrous oxide and water vapour, trap heat from the sun and warm the Earth.
Choosing renewable energy sources helps reduce the impact of our energy use on the environment. In B.C., most electricity is generated from water, a clean and renewable source. Non-renewable energy sources have a greater impact on the environment than renewable energy sources. Burning fossil fuels for energy releases greenhouse gases and carbon into the environment that had previously been trapped underground.
This activity provides a link to the core competencies of the curriculum. The activity engages students in learning about different types of lighting, which options are best and how we can all participate in using less energy.
Relevant core competencies:
Personal & Social
The activities also connect to a variety of grade-specific curricular competencies and content in a variety of subjects including Science, Applied Design, Skills and Technologies, and Physical and Health Education.
