It would take far less than 1% of the Earth’s land area covered in solar panels to supply all of the world’s electricity needs.
Did you know the average roof collects 600 gallons of water for every inch of rainfall?
The highest amount of rainfall ever recorded in 24 hours is 71.9 inches in Foc-Foc, La Réunion. This occurred during tropical cyclone Denise on January 8, 1966
A professor at Ohio State University invented the first geothermal heating system in 1948.
The Earth receives more energy from the sun in an hour than is used in the entire world in one year.
Our atmosphere contains more water as vapor than all the rivers in the world combined. If this vapor came down as water it would be enough to cover the whole world with about an inch of water.
Water can dissolve many substances, more than any other liquids. Even sulfuric acid cannot dissolve as many substances as water.
In some parts of Iceland, hot water runs from geothermal power plants under pavements and roads to help melt ice.
The amount of energy that goes into creating solar panels is paid back through clean electricity production within anywhere from 1-2 years.
Egyptians used water wheels for grinding grain for more than 2,000 years ago.
When an electric charge builds up on the surface of an object it creates static electricity, when the electric charge is quickly neutralized by an opposite charge, it creates a “shock”
In 1941, Russell Ohl invented the solar cell, shortly after the invention of the transistor.
Rain occurs on other planets in our Solar System but it is different from the rain we experience here on Earth. For example, rain on Venus is made of sulfuric acid and due to the intense heat it evaporates before it even reaches the surface!
A solar panel can work for decades. Some installed in the 1970’s are still generating electricity .
The first geothermal power plant opened in California in 1921.
Wind is a form of solar power, created by the uneven heating of the Earth’s surface.
Electricity plays a role in the way your heart beats. Muscle cells in the heart are contracted by electricity going through the heart.
Other animals can see parts of the spectrum that humans can’t. For example, a large number of insects can see ultraviolet (UV) light.
Weight for weight, silicon solar cells generate the same amount of electricity over their lifetime as nuclear fuel rods – and are much safer!
The water consumption in the United States is about 400 billion gallons a day
Water is the most commonly used renewable energy resource in the world, providing enough power to meet the needs of 28.3 million people.
The oldest known spa fed from a hot spring is believed to be a stone pool found on Lisan Mountain in China, built in the 3rd century BC
Rain contains more than just water. It might contain dirt, dust, insects, or grass
1864, a hotel in Oregon heated rooms using geothermal energy from underground hot springs.
The world’s biggest source of energy for producing electricity comes from coal. The burning of coal in furnaces heats boiler water until it becomes steam which then spins turbines attached to generators.
Electric eels can produce strong electric shocks of around 500 volts for both self-defense and hunting.
If all the rooftops in Australia were covered with solar panels, it would supply all the nation’s electricity needs.
In 1839 Alexandre Edmond Becquerel discovered the photovoltaic effect which explains how electricity can be generated from sunlight.
Rainwater is good for plants because it is free of salts and other minerals that harm root growth
