The world seems to be failing measurably in trying to replace fossil fuel with renewable sources of fuel. There is no indication that solar power is about to take over the gigantic task of fueling our homes and industries.
There’s also nuclear fuel that has its possibilities but the dangers and extra expenses involved in supporting it diminish its benefits somewhat. And then there’s wind and water power that perhaps could provide a noticeable difference in the way we provide our heat and air-conditioning and electrical power. But still they haven’t shown their power to reduce our reliance on fossil fuel.
During the eighties, President Nixon put into effect a 55 mph speed limit to preserve gasoline which reportedly provides more mph’s at that speed than higher. When gasoline appeared to be more available, that limit was eliminated.
Now there seems to be more oil and gas available by new methods of finding and producing it and an emergency lack of it does not seem as near. So efforts to provide alternatives seem to have slowed down.
But we should never cease to seek other means of getting the power we need when our main source is not renewable. There are many ways of getting the power this earth will need in the future without relying on the one-time burning of the natural resources we would lose forever.
We must continue trying to develop those renewable resources to safeguard the civilization that has been provided by oil, gas and coal.
