03.06 Human Impacts on the Environment
Transcript of 03.06 Human Impacts on the Environment
Natural Gas: Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly includes varying amounts of other higher alkanes and even a lesser percentage of carbon dioxide, nitrogen, and hydrogen sulfide.
Solar Power: Solar power is the conversation of sunlight in electricity, either directly photovoltaics (PV), or indirectly using concentrated solar power (CSP).
Advantages/Disadvantages Of This Resource
How does collecting/using this resource effect the environment?
Natural Gas: Being that it's a fossil fuel, it produces CO2 being a greenhouse gas, therefore contributing to global warming. It's also a non renewable and therefor it is not being used in a sustainable banner.
Solar Energy: It's environmental impact constitutes one of its primary selling points, and the more effectively it can function, the better its chances of supplanting fossil fuels as our main source of energy.
Compare The Cost Of Both Resources
Natural Gas: $33.79
Solar Power: I can't seem to come across.
What technology is involved in gathering or using this resource?
Solar Power: Solar panels.
Natural Gas: Stove.
Based on your research and or the information you have leaned in lesson 3.05 and 3.06, what recommendations would you make to local officials regarding the types of resources that could be used to generate electricity?
Coal, petroleum, natural gas, nuclear power, solar, wind, hydropower, and geothermal power.
Solar Power: Solar Power is a completely renewable resource, and solar energy creates absolutely no pollution. Disadvantages, solar cells and Solar Panels that are needed to harness solar energy tend to be expensive when you first purchase them, and solar power cannot be harnessed during a storm, on a cloudy day, or at night.
Natural Gas: Burns more cleanly than the other fossil fuels, and some places will apply it to your house by way of underground pipes. Disadvantages, it can leak, potentially causing an explosion, and if your house is not properly insulated it can be very expensive.
How do we use this resource to generate electricity?
Solar Power: For a central plant, sometimes the sun is focused on a boiler, and the steam from that boiler is used to turn a generator. Another way, is to use photovoltaic panels, usually sheets of semiconductor about the size of small coffee table. When the sun shines on those, some electrical power can be extracted from the output wires.
Nuclear Gas: Its clean burning nature has become very popular fuel for the generation of electricity. In the 1970s and 1980s, the choices for the most electric utility generators were large coal or nuclear powered plants.
What are the potential hazards associated with using and this resource?
Solar Power: There are roughly two types of solar power, Thermic (Solar heating) and Electric (PV) Risks are only the risks like handling any kind of powered equipment generating/using heat or electricity.
Natural Gas: Plain and simple, it could leak and cause an explosion.
