Lots of buildings are using fossil fuels, which are both inefficient and bad for the environment. It is way more efficient to use the renewable energy sources around us. Here are 3 examples using different topics: energy transferring, energy transformation, and inducers/conductors for energy waves and electrons.
So let's start to use energy-efficient buildings that are both saving energy and reducing their carbon footprint on the planet!
This home is being efficient in terms of energy, because it is not wasting energy obtained somewhere else, but by using the flow of the water that is already there! The motion of the water turns the wheel, which then transfers its energy to a motor, which generates electricity for the house!
This home is using transformers to make electricity coming into the home safe for use! Since electricity plants are far away, the electricity traveling from there to our homes needs a lot of energy. But this can make it dangerous.
This other coil and wire then carries the electricity into the home, the voltage have being transformed into a safer level.
This home is using the energy from the sun to power it. A solar panel is a panel with a layer of glass (insulator), and a wire (conductor) of static electrons below it. It converts the sun's waves directly into electricity.
A photon from the sun passes through the glass and knocks out an electron from the wire. It's place is filled by another electron, and that electron's place is filled by another electron, and so on. Since photons are hitting the solar panels all the time, lots of electrons are getting knocked out and replaced. This creates a chain, making a flow of electricity!
So what are you waiting for? Use the already available energy sources to power your buildings!
A transformer is a nearby coil and wire next to the coil and wire that the high-voltage electricity is flowing through. The high-voltage current of electricity induces a smaller current in the other coil and wire.
