Environmental issues don't just go away until we together do something about it. So lets.
Invest in renewable energy. Stop protesting on issues that were trying to improve the environment. This is important.
We have the sun that provides energy daily everywhere. Use it -solar Panels.
The Oceans cover 70% of our earth. Use it - tidal, wave and temperature energy.
Wind is a renewable source - Use it - Wind Turbines
The sun and the earths core warms our soil. Use it - Geothermal Energy
Recycle our wastes are other renewable materials. Use it - Biomass
When things like these have so many advantages and things like fossil fuels have so many disadvantages. Its sad. Really.
Prevent disasters like oil spills and pollution. Recycle. Save money, eachother.
Save the Planet, love the Plantet.
There's only one.
Amazing? There is so many alternatives out there. But we continue to pollute everyday.
The Oceans cover more than 70% of the earth's surface. The sun's heat warms the surface of the water while the deeper it gets is cooler.
According to this website, there are three types of ocean energy
1. Closed-cycle systems: the ocean's warm surface water is used to vaporize a fluid at a low-boiling point. The vapor expands and turns a turbine. This then produces electricity.
2. Open-cycle systems: boil the seawater at low pressures. This produces steam that passes through a turbine/generator.
3. Hybrid systems: are a combination of closed-cycle and open-cycle systems.
Tides and Waves are also sources that provide energy.
A dam is constructed in the water to convert tidal energy into electricity.
This video explains wave energy:
According to this article, Ocean projects could creat 50 000 jobs by 2030.
The alternative energy companies are creating jobs, environmentally friendly and cheaper for the people.
Here's an idea replace oil companies completely. Replace them with renewable companies and tax people less than each of us is paying on gas today. We all become happy. The earth is happy and more jobs are created. Sounds impossible today. But maybe tomorrow, maybe.
According to this article the U.S. factories release over 3 million tons of toxic chemicals into the land, air and water.
Some Causes Of Pollution are;
Industrial and commercial waste
Agriculture practices
Vehicle emissions
non-renewable sources that power everyday human activities, such as electricity.
Chemical and nuclear plants
Industrial factories
Oil refineries
Human sewage
Mining
Littering
Deforestation
Tobacco smoke
Combustion of coal
Acid rain
Power plants
Manufacturing buildings
Large ships
Paint fumes
Wildfires
Nuclear weapons
Factories
Pesticides, herbicides and fertilizers
Oil spills
No matter where you go and what you do, there are remnants of pollution.
Health Affects
According to this article air pollutants may cause difficulty breathing, wheezing, coughing and aggravation of respiratory and cardiac conditions.
This can cause increased medication use, doctor or emergency room visits, more hospital admissions and even premature DEATH. Yet, we still pollute. There ARE other ways - renewable energy.
On June 5th there was a rally in Sydney Australia to encourage the government in carbon taxes. Their message was climate change is happening and we need to do something about it.
"What people are asking for is an ambitious price (on carbon), an investment in renewable energy," rally organizer and national director of GetUp, Simon Sheik, said.
So these people are willing to pay more for the damage they are causing on the earth. But that's the price you pay right? the consequence? We shouldn't be using fossil fuels in the first place, which are converted to carbon dioxide, polluting the air.
In Austrailia, Prime Minister Julia Gillard's has been repeatedly attacked against her proposed carbon tax.
Really people? Well then don't use gas it will be cheaper anyway! We need to get renewable energy in the market for cars. This is a start. How are people opposed to this? I don't get it..
do not convert hydrocarbons to carbon dioxide. By taxing carbon- the burning of fossil fuels, things such as gas, aviation fuel and natural gas will be upped in price. Therefore, hopefully more people will turn to Renewable energy.
Sun is renewable.
So far we've talked about how the earth has absorbed energy from the sun and solar panels.
What else absorbs the sun's energy?
Plants -through Photosynthesis store the sun's energy on their roots and leaves.
What is biomass?
Biomass is organic material made from microorganisms (Plants and animals).
Biomass contains stored energy from the sun. When animals eat plants the energy is passed on to animals.
Biomass is
Trees-wood
Crops
waste
manure
Biomass is when this material is burned and the energy stored is released as heat. This can produce steam for making electricity, or provide heat for homes.
It is renewable because we can always plant plants!
Many towns burn their garbage in waste-to-energy plants. Instead of putting the garbage in landfills, they burn it to make electricity.
When is the last time we had a huge technology breakthrough? Technology has increasingly been able to amaze people with the advancements but we haven't seen any huge changes in our daily lives. For example television, cars, or electricity. These were huge. Some people believe that alternative energy will be the breakthrough in technology and investors are calling it "angel investing". According to this article, they believe: "The chances of any one experiment failing may be high, but the chances of all of the experiments failing is very, very low. You should have a thousand points of innovation, and for sure you'll get a breakthrough." The grand goal is that hopefully renewable energy will replace fossil energy sources 100%. However, right now biomass, solar energy and wind energy provide 3.6 percent of the nation's energy. They have predicted that the share will grow 4.2 % by 2030. A lot of money has been poured into ideas and the generation of alternative energy. They are hoping people will invest more and more because they'll cost less than coal or oil.
Some ideas they've planned are placing 3-mile-square fields of mirrors in the desert to focus the sun's rays and shooting high-pressure water into the hot rock 3 miles underground to create a man-made geothermal reservoir.
As of now biomass is the highest renewable used alternative to fossil fuels at 3.3% (see above graph)
Like other renewable sources, it is environmentally friendly, cost efficient, and renewable.
