Introduction Firstly, I have chosen this question because it affects us globally. When the hydrocarbon crude oil, which is a non renewable fossil fuel (and cannot be used again in our lifetime), is under combustion, it gives off emissions such as C02 which is a green house gas. These gases then form a cloud that traps the suns rays from reflecting back into space, so the bounce back onto earth, shaping almost a zigzag formation. This means that the suns rays are repeatedly hitting earth, causing the temperature to rise, this is called global warming. Through global4 warming scientist have calculated that after the next 20 years the global temperature will rise by 2 degrees, not much but after the next 100 years it would be 10 degrees, a major change. ...read more.


Without crude oil my life would change dramatically, but if we keep using it our global climate will also change, there has to be another solution Renewable sources are sources of energy that can be renewed or replenished within a short space of time( e.g. the wind can be used for energy by the use of a fan shaped mechanism in which the wind blows around turning the fan = powering the turbine which generates the energy known as wind energy: There are many different types of renewable sources but the main sources naturally occur (e.g. the suns rays which is known as solar energy). ...read more.


All these arguments for the argument clearly over power the arguments against, stating that crude oil should not be used and that a new source of energy must be introduced to preserve our planet from further damage. But to summarise on whether renewable sources should replace crude oil is another matter for there are other ways such as nuclear power, but the process of building, running, dismantling is hard and the unreliable radiant gases given off hare to be trapped beneath the ground for l000s of years, taking up much of our needed land. So in conclusion though renewable are quite expensive and do rely on the environment around them, they can provide us with the energy we need with no harmful emissions given off and are very reliable, renewable sources seem to be the most logical answer. ...read more.

  1. Global warming

    The creators of this graph gathered their information on temperature from a variety of different sources including ice cores, tree rings, coral, and historical data. This data has been challenged by specialists who believe it is flawed and can no longer be viewed as valid.

  2. Global warming

    The impacts of tropospheric ozone, stratospheric ozone, and particles are quite uncertain. The red bar indicates the range of possible effects for these gases; i.e., the effect is in the range of one end of the red bar to the other.
