Answer:
As the cloud shrinks in size, its central temperature increases, as a result of its gravitational potential energy being converted to thermal energy.
We are assuming that the mentioned cloud, is a cloud of interstellar dust (nebula), in which this definition is applicable. Since energy cannot disappear, the lost gravitational potential energy would have to transform into something else, in this case, thermal energy, or simply heat, which will increase the overall temperature of the cloud.
The development of renewable resources has the goal of reducing greenhouse gasses in the atmosphere.
In the last decades there has been increased effects on the climate and atmosphere on our planet, and it is obvious that the reason for that are the human activities and the usage of fossil fuels and coal. Because of this people have started to develop and invest more and more into the renewable resources, thus step by step replacing the fossil fuels and coal, and protect the environment.
