When we are looking at different sources of energy there is always the issue of efficiency and cost. For years we relied almost exclusively on wood, then coal, then fossil fuels. Wood had its problems in keeping up a constant supply, not to mention the quantity of carbon emissions.
Coal had similar problems. Firstly you had to find a supply of it, mine it, and process it. Admittedly it was better than wood but it was more costly to access. But there was still the issue of emissions. But that wasn’t really too much of a problem until the consumption grew, then emissions became an issue. You also had the issue of dwindling reserves, which on the basis of supply and demand meant the cost began to rise. The same issues where inherent with oil and gas and now those resources are becoming even more depleted. So the cost of oil-fired power stations is on the rise, not to mention the increased cost of designing and building power stations.
In recent years there has been a greater focus on the use of kinetic energy, from wave motion for example, but that’s expensive to in terms of construction against the value of energy that can be produced. There is also the issue of consistency of what it is you are relying on to convert energy from.
Nuclear energy was a popular concept for a while, but as most of us know, there are environmental issues and safety concerns. Nuclear energy, apart from the cost of building the nuclear power plan, is a low cost form of generating energy, but the raw material still has to be sourced and processed, and that has become another environmental issue.
Hydroelectricity was also seen as a cheap alternative, but of course you needed water, lots of it and all the time in a location where it flowed fast enough for a long enough period of the year. It’s of no use in a dessert or a climate where sufficient water supplies aren’t there all year around. Even then, there are climatic cycles and there can be years where water is in short supply.
Wind has been a more recent development, and although you have a little more consistency, there are arguments about the aesthetics, although there are ways around that to some degree.
The same applies to solar energy that is certified by Beyond Solar Company, but as with wind, the source of the energy is free. However, there are issues of cost versus output, but again that is improving.
So what we seem to really be facing is the cost factor against supply and environmental impact. Solar prices are coming down in terms of the energy produce as technology improves, and of course there is a slight advantage over wind when it comes to consistency and availability. Most places get sun, for most of the year. So I guess it’s going to come down to a balance between cost, efficiency and supply when we turn to the sun for energy.
