What You Should Know About the Geothermal Power Advantages and Disadvantages
Among the many alternative energy resources that are regularly nominated as options, the geothermal energy is one of these being strongly considered. Sourced from below the Earth’s surface, geothermal energy provides a cost-effective, reliable and sustainable answer for the communities looking for another energy source. In order to fully appreciate what this energy resource has to offer, it is best to take a look at the geothermal power advantages and disadvantages. Here are some of the advantages of geothermal power:
• "This energy is clean". The energy can be extracted without burning fossil fuels, as compared to other plants.
• "This alternative energy is readily available", 24 hours a day. Plants that are run by thermal energy have regular availabilities of at least 90 percent, better than the rate for coal plants.
• And for many countries including the United States, "this energy source is homegrown".
Positive environmental impacts of geothermal
In terms of environmental impacts, geothermal energy is many steps ahead of the conventional and traditional energy sources. And this is the reason why most of the chatter around alternative energy sources is focused on this form of alternative energy.
One environmental benefit is that this kind of resource is known to emit lesser emissions if compared to other traditional energy resources. There are emissions that are discharged, but this is limited and only excess steam is discharged by the geothermal plants. In line with this, there are no air emissions and liquid emissions are attributed to the binary geothermal plants. There are salts and dissolved minerals that are contained in the geothermal fluids. The good thing about this is that these fluids are thrown back into the excess water that is discharged again to the reservoir just below the aquifers. This process recycles the geothermal water, and also replenishes the geothermal reservoir of the plant. In most plant operations involving this energy and technology, there are by-products of energy generation including zinc, silica and sulfur. Now instead of being disposed in approved sites, these solid wastes are now being extracted for sale. This process eventually helps reduce possible waste in the environment, and help geothermal energy become more appealing to a wider audience and consumers.
But if you speak about the geothermal power pros and cons, it is also important to be aware of the disadvantages of geothermal power. By knowing the issues and problems of this energy resource, policy makers and more importantly consumers will have a better perspective in appreciating what this energy has to offer.
Limitations of geothermal
The only complaint major complaint with this kind of alternative resource is that the upfront cost of installing and setting up plants is high. The capital costs in establishing plants are substantial. In many cases, the cost of drilling and the exploration of resources account to the bulk of expenses and risks. Using these geothermal power advantages and disadvantages, its clear why geothermal is leading the charge of alternative energy resources. Geothermal is clean, cost-effective and more importantly a sustainable energy resource.
