That might be changing. No, I’m not putting solar on my roof. Too expensive. I’ve done the standard home efficiency upgrades — insulation, windows, doors, new 95 percent efficient furnace. But that’s another story.
Once a suitable salt bed or dome is found, it needs to be hollowed out into a cavern or basically a very large holding tank. The cavern walls are impermeable and can withstand extreme pressure. The caverns can be shaped to be as big as needed and that of which will allow. How is this man-made cavern created in salt? In most case, it is by a process of solution mining. This just means highly pressurized water flow is pumped through a pre-drilled well in the layer of salt that will dissolve the salt. The dissolved salt is then cycled back up the well and piped off to another location.
Speaking of which, what could be more sustainable than solar? It’s not as if the sun is going to burn out any time soon. The average photovoltaic (PV) array has a life expectancy of 40 years now (their warranties are usually 25 years) and pays for itself after only 8-10 years, depending on the location. Very few investments will pay that kind of guaranteed return. After ten years, you’re getting free electricity for the next 15-30 years. Not bad. Actually, if energy prices keep rising as seems likely with billions of new consumers online in China and India, your PV array could turn out to be quite the bonanza from an investment standpoint.
The U.S. is definitely not immune to the possibility of what is know as hyper inflation. This is where the costs of everyday goods go through the roof. The result is the loss in value of the American dollar. If this happens, the dollar will only buy a fraction of what it can buy today.
After talking about fossil fuel and what will happen if we are running out of fuel ( so-called energy crisis ), let us go straightly into our topic today, the renewable energy. Normally, renewable power supplier sources like wind power, tidal power and hydropower is used to generate electricity.
One of the striking sights of the city is the Jet d’Eau. It is a water fountain with beautiful lighting in the night. It was created due to the pressure released during hydropower generation in the Rhone River. It soon turned into an attraction and was then made a permanent feature of the city. There are a number of churches and cathedrals to explore. St. Pierre’s Cathedral is an extremely popular attraction in the city. There are a number of museums and art galleries to see as well.
Your electricity produces a “carbon footprint” depending on the mix of fuels used for power generation. Your home carbon footprint depends on how many kilowatt-hours (kWhs) of that electricity you use at home.
People and businesses taking advantage of this technology today are the people and businesses of the future. But solar power is here now, and it is here to stay.
