Which is the principle behind wetlands-based sewage treatment systems? Use natural processes in a series of tanks filled with aquatic plants. When water absorbs carbon dioxide they become less acidic. Which type of fertilizer has the greatest potential to contaminate streams?,
Advantage: uses sun panels to power homes and heat water and homes. Disadvantage: high cost of solar cells and requires lots of cells to power a city, very expensive. Disadvantage: large scale use limited to areas with strong winds, built in country far from cities.
The Disadvantages of Solar Energy One of the biggest problems that solar energy technology poses is that energy is only generated while the sun is shining. That means nighttime and overcast days can interrupt the supply.
Expensive Equipment Cost The major drawback of Concentrated Solar Power Plants is that capital cost and maintenance cost is more expensive than other power stations. It is even more expensive than Solar PV Plants.
Modern landfills have multiple cells, and when a cell is filled to the brim, it is capped with an impermeable material (such as clay and/or synthetic liners), then a layer of soil, and then planted with native grasses. Capping reduces the amount of leachate, as rain and snow melt no longer infiltrate the waste.Apr 18, 2018
Landfills are regulated under RCRA Subtitle D (solid waste) and Subtitle C (hazardous waste) or under the Toxic Substances Control Act (TSCA).Feb 23, 2021
Identify the drawbacks of solar thermal systems. The drawbacks of solar thermal systems are low net energy, high costs, need for a backup storage system on cloudy days, high water use for cooling, and possible disruption of desert ecosystems. Identify the benefits and drawbacks of solar cells.
New landfills are required to have clay or synthetic liners and leachate (liquid from a landfill containing contaminants) collection sys- tems to protect ground water. Most older land- fills, however, do not have these safeguards.
