Trees produce flowers, photosynthesis, and rain, wind, heat, and coolness.
We feel the light and warmth of the sun directly, and the energy contained in it resides in nature in many ways.
In addition, solar energy affects energy sources that directly affect the existence of the world today.
Geothermal energy is one such source. It is a renewable energy source that extends from liquids and rocks on the Earth's surface to hot rocks (molten rocks) and magma.
There are currently three types of geothermal power plants in the world: dry current, flash and binary, and hot water canals are dug as appropriate for underground reservoirs to generate electricity from existing geothermal power wells. The water received through it is used to operate the turbines connected to the generators.
This energy is used for direct use in food processing, fruit drying and refrigeration, fish hatcheries, agriculture, recreation and tourism.
The most active geothermal resources are usually bordering major plateaus ("Ring of fire"), which are concentrated in earthquakes and volcanoes. Experiments have now revealed that it is in the range of up to.
Our past book testifies that hot springs and hot mineral springs have been used for recreational and health purposes for centuries. There are reports of many heated swimming pools, mineral baths, steam baths, and specially organized recreation centers in several countries. Heat springs in Sri Lanka have been used for the above purposes since ancient times but they need to be developed in a modern way.
These areas have a dry climate and the main economic activity of the area is agriculture. It is also a popular tourist destination and in recent years the tourism industry in the tropics has grown significantly. The area from Trincomalee to Hambantota in particular is home to wildlife and beautiful beaches.
About 9/10 of Sri Lanka consists of proterozoic and metamorphic rocks, the remaining 10% being mostly phenarozoic and recently accumulated sedimentary rocks and surface deposits.
The location of the heat source and the depth of the reservoir are essential for obtaining geothermal energy and should be an economically accessible area.
Using modern geophysical and geochemical methods, it has been revealed that Nelumwewa, Mahapelessa, Kinniya and Kapurella hot springs are deeply located. Can do. Other hot springs found during excavations can also be used for other heat applications.
Great benefits can be derived from geothermal energy as a direct benefit. These include hot water as an energy source for drying agricultural products (cereals), sugar processing, paper mill operations, pulp processing for paper production, preservation of fresh vegetables, fruits, meat and beverages. Use of geothermal energy in such sectors Price The need to use high and environmentally friendly fossil fuels will be replaced. Such applications also pave the way for effective employment opportunities that lead to poverty reduction.
Given the high initial cost of geothermal energy and the technical know-how required to use heavy metal sources such as greenhouse gases, arsenic, boron and mercury, this could pose some problems for Sri Lanka. Care should be taken to carry out technical activities in this regard in line with the existing agricultural and tourism activities in the area. In the face of the crisis facing the entire world today due to the focus on only a few energy resources, each country must find a solution to this crisis. Otherwise, the energy crisis will hamper the progress of the whole of human society.
As geothermal energy is a renewable energy source and an environmentally friendly energy source, geothermal should have a special place in power generation in the face of future energy crises.
As you read this article, you may be wondering why this little island, rich in natural resources, has been a developing country until recently. So today the world uses advanced technological knowledge to generate energy for various purposes from the waves rising from the ocean. Sri Lanka, surrounded by the Indian Ocean on all fours, has a high potential to generate this energy. We are slowly coming to the end of our journey in search of a renewable energy heritage. So in the last article we will meet about the Sri Lankan economy that can be revived by the waves of the Indian Ocean. Stay tuned with Green Hearts
