Energy



Philadelphia placed 500 solar high tech trash-cans in the downtown area of the city. The trash cans use energy to condense the trash. The energy is produced by sunlight. When the sunlight hits the trash-cans, it pushes the trash down to make space for more. The trash-cans cut trash collection by 75% which saves a lot of energy and gas. The trash-cans were purchased with state grant money. The city estimates the trash cans will save $875,000 a year.

These solar powered trash cans are related to the bigger theme of energy because they were created so that the city of Philadelphia can rely on energy from the sun to save money. All over the world, cities and individual states are trying to develop ways to conserve energy and use energy in different ways because resources are so limited now. By conserving energy, we are preventing the misuse of the few resources that we have now that we have taking advantage of as citizens.
