Promising Alternative Sources of Clean Energy: Wind and Solar

Promising Alternative Sources of Clean Energy: Wind and Solar

Renewable energy is a form of energy produced from natural sources that are continually replenished, environmentally sustainable and economically viable. Wind turbines and solar panels have proven to be promising sources of renewable energy. Wind powered generators are becoming increasingly popular in the United States.  Last January, wind power contributed to over 4% of US electricity. Only a few years ago, people were not so sure about wind powered generators.

Global Awareness – Top 5 Environmental Issues

Global Awareness – Top 5 Environmental Issues

This week we are going to discuss 5 environmental issues that you should be aware of. These issues are global and may concern some readers more than others. As usual, these issues are not written in any particular order of importance.

1. Finding alternate clean source of energy

High gas prices and the monopoly of oil companies are once again making us exhausted, and wearing our wallets out. We have drilled more oil wells in the United States in the past decade than anywhere else in the world. Furthermore, we pay about $4 billion dollars to oil and gas companies as tax breaks. Still we have seen nothing that could ease the prices at gas pumps. Gas prices continue to hit new heights, and we are still hostage to oil and gas companies for our energy requirements. Drilling new wells only makes gas companies more profit, and has done nothing for the consumers. We often hear that nothing can be done here in the United States because gas prices are set by the global marketplace.

Given an option, we would not have to depend on gas as much, and the prices would also decrease about $4,400 a year. We need alternative sources of energy to help ensure a cleaner environment as well as to reduce our dependency on gasoline.

Concerns About Species Of Living Things Extinction & Ecosystem

Concerns About Species Of Living Things Extinction & Ecosystem

In order for the ecosystem to function properly, all species of plants animals and insects, and all types of living and non living things such as air water, soil and so on must stay in harmony. Mother Nature has perfected a system of balance where all different species of animal coexist. They even help each other to survive and grow as they balance out in the ecosystem. Each element of the ecosystem plays an important role, and so, it is important that each species of plants or animals remain in the ecosystem and interact in order to make the ecosystem work.

The Causes And Effects Of Global Climatic Changes

The Causes And Effects Of Global Climatic Changes

Climatic changes and the global temperature have always been very dynamic. It’s the result of a balance between the total amount of energy entering and leaving the earth. The earth has been balancing its temperature since the day it came into existence by absorbing heat from the sun and radiating it back into the atmosphere.

Most of us learned in our high school geography class that the earth receives heat from the sun through solar radiation, and then cools off at night by radiating the heat back into the atmosphere, and thus a balance is reached. Many factors, which are both naturally occurring and triggered by human activity, can influence or interfere with this balance.
