Fuel and Oil or Renewable Energy?
Battery efficiency and the costs of enough solar energy storage are two of the main obstacles as far as solar power completely replacing oil and other fuel sources. The current technology of home solar power system batteries often isn’t strong enough to store enough energy needed for longer periods without direct sunlight. This could definitely spell problems for solar panel owners in some geographic regions of the northern hemisphere, such as Scandinavia and Northern Canada. For certain stretches of the year, these countries experience as much as 20 hours per day of darkness, likely making sufficient solar energy storage a serious strain on home systems’ batteries.
So, as much as solar energy is a great replacement for fossil fuel, it still needs to overcome a few obstacles before it can become a real option. For the time being, fuel and oil are the more convenient options we have.
