I expect if you have an automobile that runs on gasoline and a furnace that burns oil then the answer for you is yes.
If you have a natural gas furnace you will need natural gas to run that.
If you are choosing something new, you will need to do your own cost benefit analysis to determine if the technology is proven and cost effective unless you are willing to pay the premium for unproven or less than cost efficient/effective technologies.
It appears that many preach alternatives but fail to act. Al Gore is a prime example. While preaching all alternatives his home used massive amounts of resources (you can look it up). Until he was called on it he hadn’t made any modifications. After being called on it he has since, I believe, made some modifications. He is pretty much a phony.
Now if one is wealthy, they could take all these great cutting edge technologies and install many of these systems in their homes and the cost be dammed, but if you have an existing structure, the cost of these systems for the average man or woman will/could be excessive.
Now if you are an activist and your first impulse is to just hate the oil companies, I expect the best thing for you would be to stop using oil and use alternative products for your energy needs. That effort will have a two-fold benefit. You will feel better by not using the dreaded product “oil” from your enemy the oil companies and it will leave more oil available for your fellow citizens, that don’t share your hatred of oil and oil companies, to use. It may cost you more but there is a premium to being on the leading or cutting edge of anything.
