good question, alot, GO OUTSIDE
shorter showers, carpool, public transportation, turning off the lights when you leave the room, anything that doesn't use energy
boobs.
You could turn them off.
carbon offsets
Leaving lights on when not needed contributes to energy waste, increases electricity bills, and has a negative impact on the environment by producing more greenhouse gas emissions from power plants. It is important to turn off lights when they are not in use to conserve energy and reduce our carbon footprint.
According to science, if society does not conserve energy, fossil fuels will be exhausted. That could be a disaster for future generations.
Over time, a smart house could conserve a lot of energy (minimize the energy wasted). For example, the lights would go out when you leave the room. Another example, of smart design: the heat from the back of the refrigerator would be used to pre-heat your hot water.
Use solar panels to capture sunlight and convert it into electricity. Install energy-efficient appliances and lighting to reduce energy consumption. Implement passive solar design techniques in buildings to maximize natural light and heat. Use solar water heaters to heat water using solar energy.
Turning off lights in a classroom can save a significant amount of energy, depending on the type and number of lights being used. On average, the energy saved could range from a few hundred to a few thousand watts per hour. Over time, these energy savings can add up and contribute to a more sustainable environment.
Photosynthesis requires energy from light. If there is no light there can be no photosynthesis. Photosynthesis doesn't occur in the dark. You could use electric lights to simulate daylight and make plants photosynthesise during the night time.
Conserve and recycle.
You could (when your about or are leaving class) remind your teacher to turn off all lights and computers
