Global warming! !! Oil!!! Polar bear !!! I will talk to you today about energy and global warming Coal!!!
Energy has the ability to make things happen , cause changes and carry out work. Any change in the universe, from a tiny meteorite hitting a planet to an exploding star , means that energy is busy. In daily life , energy is all around us in many different forms. light and sound energy travail through air waves. Heat is a form known as thermal energy. movement energy or motion is also known as kinetic energy. Objects even have energy because of there place or position this is called potential energy. A bolder on a hill top has potential energy because gravity tries to pull it down as the bolder rolls down the hill the potential energy terns in to kinetic energy.
Energy is all around us presented in different forms and changing from one form to another with out energy our world would be completely cold, dark, still and silent.
Energy forms are either potential or kinetic. Potential energy comes in forms that are stored including — chemical, gravitational, mechanical, and nuclear. Kinetic energy forms are doing work — like electrical, heat, light, motion, and sound. We use loads of energy in our houses , in work , in industry , and for personal travel and transporting things.
!!!!There are 2 types of energy !!!! Renewable energy sources including biomass, hydropower, geothermal, wind and solar provide 7% of the energy used in the UK. Most renewable energy goes to producing electricity around the world. Non-renewable !!! About 93% of the energy consumed in the UK comes from non-renewable energy sources, which include fossil fuels — coal, green house gases, and petroleum. which causes a lot or Eco problems throughout the world.
Advantages of renewable energy ! Advantages of nonrenewable energy! Some advantages of renewable energy are : Some advantages of non-renewable energy are : it doesn't harm the environment. its easy to find. it is lower costs than fossil flues. its widely available. Disadvantages of renewable energy ! Disadvantages of non renewable energy ! Some disadvantages of renewable energy are: Some disadvantages of non-renewable energy are: that with solar and wind energy you need sun and wind and if the weather is neither sunny of windy then it is useless. that it is no good for our environment. Transporting coal and oil causes pollution.
In 2008, 79% of UK carbon dioxide emissions came from the use of coal and petroleum fuels. Energy sources have different impacts and affects on the environment. Some of these affects may include emissions, waste on land water. The energy sources we use to make electricity can be renewable or nonrenewable, but electricity itself is neither renewable nor non-renewable. Fire was civilisation's first great energy invention, and wood was the main fuel for ages.
the burning of fossil fuels like oil and coal cause greenhouse gases to escape into the air and that these gases are causing most of the warming. Another cause is deforestation (cutting down trees). Trees soak up carbon dioxide, one of the greenhouse gases, from the air. "Global warming" refers to the increase of the Earth's average surface temperature, due to a build-up of greenhouse gases in the atmosphere. "Climate change" is a broader term that refers to long-term changes in climate, including average temperature and precipitation (rain).
Here are some pictures of the consequences of what is happening around the world due to the use of fossil flues and non renewable energy!!!!!!
