What are benefits of oil?
Oil: lifeblood of the industrialised nations Oil has become the world’s most important source of energy since the mid-1950s.
Its products underpin modern society, mainly supplying energy to power industry, heat homes and provide fuel for vehicles and aeroplanes to carry goods and people all over the world..
What are advantages of electrical energy?
It can be used produce magnetic fields, which can be used to propel motors. It is very transformable. It is very fast, virtually the speed of light. It can be used to produce other forms of radiant energy, such as radio waves, microwaves, radiant heat and light.
What are the pros and cons of electricity?

How electricity affects our lives?
Electricity has made the economy active all day, every day. Factories and retail outlets can now operate around-the-clock. Electricity make cities safer, as city lights are cheaper to operate on electricity rather than whale oil. … Electricity also keeps people alive in hospitals through ventilators and monitors.
What are the negative effects of electricity?
Pollution and Acid Rain Almost all forms of electricity generate waste. For example, natural gas releases carbon dioxide and nitrogen oxide. Earth’s atmosphere traps these gases, leading to air pollution and smog. Weather patterns and geological variations can affect the prevalence of smog in a particular area.
What are the disadvantages of electrical energy?
High cost of designing and building nuclear power station.Waste in the form of used fuel rods which are very hot and highly radioactive.Hot water discharged causes thermal pollution to the environment.Risk of accidents which may lead to the leakage of large amounts of radioactive substances to the environment.More items…•
What is a disadvantage of oil?
Oil is a non-renewable source of energy. This means that one day we will probably run out of crude oil. Burning oil produces carbon dioxide gas. … Burning oil can pollute the air. Much of our oil has to be imported and it is becoming more and more expensive as reserves reduce and imports increase.
What are the advantages and disadvantages of electric current?

What are 5 Advantages of oil?
Advantages of Oil EnergyOil has High Energy Density. … Oil is Easily Available. … Oil is Used in a Variety of Industries. … Oil is a Constant Power Source. … Emission of Greenhouse Gases. … Water Pollution. … Oil Refining Produces Highly Toxic Substances.
What are the three uses of electricity?
People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems.
What is a power?
In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.
Why is oil the most used source of energy?
Oil is particularly useful as a fuel because of its high energy density. As previously mentioned, the original energy source of oil is the Sun, as the energy stored within dead organic matter is what creates crude oil over time.
