It seems that LCD TV’s are environmentally friendly if you want good quality and low energy consumption.

Plasma: This particular TV display is probably the worst eco-friendly option to choose. While the picture is sharp and clear, “producing that perfect image requires a high resolution, and the higher the resolution, the more bandwidth—the rate at which data is transferred—the set needs,” according to GetDirectTV. Also, with any television, size matters. The bigger the set, the more energy and light it will take to illuminate the screen.

LCD: These sets seem to be somewhere in between Plasma and LED choices. While the technology of an LCD TV uses about a third of the energy consumption than Plasma, they still don’t quite beat the innovative technology of an LED TV.

One of the best tips for choosing a more environmentally-friendly television is to look at the Energy-Star rating that can be found on each TV display. And of course, as stated earlier, size does matter! Regardless of what kind of television you choose, the size will make the biggest impact. Remember, the bigger the size, the more energy consumption it requires. Not to say you have to sacrifice size or quality, but the amount of energy consumption is something to keep in mind.

Underground springs that bring melted snow water underground to a surface source are cold even in the middle of summer. The ground insulates the water that entered the aquifer at cold high altitudes keeping it cold regardless of air temperatures.

Underground springs, known as hot springs, get their heat by contact with the heated magma underneath the earth's surface. This hot springs will be close to boiling hot even in the middle of winter when there is snow on the ground.

The temperature of underground water sources depends on the source of the water not the air temperatures.

Biomass energy : The dilemma is "Food for people or food for energy?". It is good if a country can provide land for biomass production and does not encounter food deficiency.

Geothermal energy: In some areas the geothermal gradient is sufficient enough to exploit to generate electricity. Disadvantage of it is that geothermal liquids contain many different types of minerals and elements. When they are allowed to flow free, they might pollute the environment (for example in Aydin Buharkent Turkey).

Wind energy: When wind is in sufficient velocity, people want to benefit from it by using wind turbines. The disadvantages of it can be listed as: some birds and bats as well as bees die when this turbines are operated, a certain amount of land (a quarter US acre for example) is necessary to erect wind turbines (wind power company has to cut down trees and clear the area), noise pollution, etc.

Tidal power : During high-tide event store sea water and then when it is low-tide people can produce electric by operating specific turbines. The disadvantages of it are that not everywhere you can see this activity, some fish species might be affected, you disturb some coastal areas, etc.

Solar power: PV technology depends on sunshine. Under sunny conditions, mild (in terms of wind) conditions and less dusty (particulate matter) circumstances, photovoltaics can provide electricity. You need free land to build PV arrays. Some people argue that some birds and other avians are negatively affected by such structures.

Hydroelectric (dams): Water is cycled in nature. When you build a dam on suitable places on a river, you can store water and produce electricity by operating turbines. There are some disadvantages of such structures. First, stagnant water bodies do not oxygenate (aerate) easily compared to that in streams (rivers). Therefore, they are delicate to pollution. Moreover, some migrating fish species could not move towards upstream. They are badly affected. Finally, such large dams slow down the rotational velocity of the earth.

There are many issues related to renewable energy indeed. I was warned that I have provided a long answer. So far, that is it.

The process of photosynthesis uses Carbon Dioxide as a reactant removing the Carbon Dioxide from the atmosphere. The reduction of Carbon Dioxide from the atmosphere helps to reduce global warming.

During the Mesozoic Era there were high levels of Carbon Dioxide that resulted in high levels of photosynthesis. The era of high carbon dioxide is also known as the Carboniferous Era. The High levels of Carbon Dioxide created large amounts of plant growth that created the coal deposits.

High levels of photosynthesis take large amounts of Carbon Dioxide out of the atmosphere to create sugars and starches used for plant growth.

As temperature and precipitation decrease, biodiversity generally decreases.

High species diversity :

Tropical forests are widely considered to have the greatest species diversity of the terrestrial biomes but diversity is also high in the temperate deciduous biome and

Low species diversity :

The tundra biome has the least biodiversity, but the northern coniferous biome also has low species diversity. Generally speaking, desert biomes have low species diversity, but pockets of localized high biodiversity do exist. You can read more about exceptions [here] (http://www.conservationmagazine.org/2015/03/deserts-teem-with-biodiversity-if-you-know-where-to-look/) and here.
