A Comparison Of Wind, Solar, And Geothermal Energy Sources
The wind, solar, and geothermal energies have two important things in common. They are non-polluting and do no deplete precious Earth resources. However, there are differences in their cost-effectiveness and environmental imprint.
The wind is actually a form of solar energy. Air moves as the sun warms the irregular terrain of Earth unevenly. Bodies of water and vegetation contributes to the flow. When gusts move the “propeller” of a wind turbine the kinetic energy generated is converted to mechanical force. This can be turned into the electricity we all depend on.
There are a couple things to consider before using gusts of air as an energy source. Some parts of the globe are much windier than others. When it comes to cost effectiveness, having more current is efficacious. The turbines have a detrimental effect on local wildlife as well. The spinning blades strike unsuspecting bats and birds causing them an untimely death.
Solar panels have become a familiar sight in many parts of the world. To use the sun’s light for power its rays are captured by different types of collectors (material that absorbs light). This can provide direct heat or is converted into another power source. One type of collector, photovoltaic cells, changes sunlight directly into electricity. Flat-plate collectors warm water by absorbing heat directly into it.
Harnessing sunlight is free from pollutants and kind to the environment. One drawback is we can only collect sunlight half the day. In colder regions, hours of sunlight diminish further. Another problem is that equipment to collect, or store light can be expensive and their production may release contaminants. It is cheaper to get electricity from the fossil fuels than the sun.
The Earth’s core is extremely hot. Temperatures there can reach above 9,000 degrees F. This heat flows outward and warms the planet’s rock layer, or mantle. Most of the heated rock, called magma, remains underground. The force collected there (a geothermal reservoir) can be harvested as steam or hot water from the underground via direct-use systems, deep reservoirs to generate electricity, and geothermal heat pumps. Emissions and environmental imprint are minimal. The supply of geothermal dynamism is reliable and always available, increasing efficiency.
Nature provides solar, the wind, and geothermal energies free from charge but using them still costs money. Structures built to harness and use renewable sources may generate contaminants and can be costly. To choose the most suitable power, geographic location, financial concerns, and ecological imprint must be considered.
