Geothermal Energy: A Solution to the Energy Crisis

Abstract
So far, scientists have not found a successful substitute for fossil fuels that can handle both the large demand for energy and solve the global warming problem. I propose that geothermal energy is a clean, widely available, and renewable alternative to the usage of fossil fuels. In this paper, I will explain how use of geothermal resources can be energy-efficient, environmentally clean, and cost-effective. I believe that the US government should increase funding for geothermal energy research. This may be the solution to our present energy crisis and global warming.
Introduction
There is a call of action to solve today’s energy crisis. What we need urgently is a clean

Fossil fuels (oil, coal, natural gas) take up about 80 % of total energy consumed. Fossil fuels cause pollution and global warming yet we continue to use them. Our demand for fossil fuels has become so great that according to current projections, Earth’s reserves will be depleted within the next 200 years. But we do not actually have 200 years to wait. Our run-away consumption of fossil fuel not only endangers our ability to meet our future energy needs but also the environment. Fossil fuels cause significant pollution and global warming. This in turn compromises wildlife habitats and can even lead to extinction of animal and plant species. By looking at new sources such as geothermal energy, we can move towards a source that is not extremely harmful and yet still effective.
Geothermal Energy
Geothermal energy is heat energy that is stored underneath Earth’s surface. It is mainly found at volcanoes, hot springs, or geysers. Heat stored in the hot water and steam found at these locations is captured and can be used to heat buildings or generate electricity. This energy source is renewable because heat from the earth is continuously produced. To obtain energy, you must either use hot water or steam from the source. The most common way of capturing the energy from geothermal sources is to tap into naturally occurring “hydrothermal convection” systems where cooler water seeps into Earth’s crust, is heated up, and then rises to the…
