investing in oil is good idea .but u should not invest it more than 30 years from now .because 50 percent of the energ resources in the world would depend on renewable resources and the cars would all be electric cars and electric stations would be installed in quite a few place .
But to me I think investment in oil is still a good idea, no doubt that car will start using electric resourses, but I think the importance of oil cannot be decrease yes, as the resource of oil are decreasing from time to time therefore the supply will reduce and the demand will increase and so the price of oil will also increase so much, therefore to me investment in oil is not a bad idea.
Oil still have a bright future, you are all forgetting some of the most important points here :
1- Renewable resources are expensive to process.
2- 80% of the countries in the world are called "3rd World".
3- Only the "G21" is concerned by the renewable energy, and it is just 21 countries.
4- The cheapest energy is provided by oil (electric central, cars, manufactures ... )
5- The actual investments will feed the market for decades.
That's why oil market will exist for a long time, and his importance if far from dropping. Let's say that G21 decides not use any more OIL, and then ? There will always be 80% of the world to consume it, and because of how capitalism works the G21 will return to its usage because of the lowered price. So you should carefully understand the OIL ecosystem and consumption before thinking that the "world" will turn green. I know a lot of countries who can't even imagine living without OIL. G21 is the exception, not the rule.
