EPA , is proposal clean power plan to cut carbon pollution from power plants by 30 % , by the 2030 . If we look across the USA power sector , the proposal will boost the UAS economy , protect heath and environment and fight climate change .The US supply the electricity every day form coal , natural gas , hydropower ,nuclear ,wind and solar .

 

When fossil fuel like coal are burned to produce electricity , they release CO , which lead to trap the heat and this will lead to claimant change . According to EPA the best way to cut down carbon pollution  is to generate more power from the cleanest sources and use the energy  more efficiency . The EPA explained that each part in their system offer huge opportunities  to reduce the pollution that lead to claimant change . Also they expecting to make improvement at power plans , expand renewable energy production ,generate more of clean energy and increase energy efficiency .

 

Some Benefits That are Expected From This Proposal:

For every dollar invested in this plan there will be 7 dollar benefits and by 2030 there will be between 55 – 93 billon dollar of net claimant and heath benefits. The proposal is going to increase energy efficiency and clean energy investment. In fact one study has shown that there could be 274000 new jobs associated with this proposal.

 

EPA mentioned that the most immediate impact of this proposal is going to be improved health for many Americans. it is estimated that in the first year this proposal will prevent 100000 asthma attack because of reduced partial pollution , also it is estimated to reduce 2100 heart attack in it’s first year . They expect that 6600 premature heath will be avoided as a result of this proposal.

 

EPA estimated that in 2030 will be an 8 % decrease in the electricity bills. This is because there will be an increase in energy efficiency and the cost of employing clean energy will go down. EPA explained that one of the reasons that this proposal is so achievable is that it is NOT a top down approach. The proposal plan allowed states to chose what works for them, with the recognition that what works for Ohio may not be the best solution for Taxes and vice verse.

Ways  to Increase Gas Mileage

There are many way that automakers using to increase gas mileage and enhancing the performance of the cars

Hybrid car

A hybrid car is a vehicle that uses two or more distinct power sources to move the vehicle . it gives the best of both , it combine  the power and the rang electrical engine with environmental benefits of an electric motor . It takes off at low speed , the car will run on electric power only which mean zero fuel consumption . Under high acceleration the petrol engine kicks in and take over the job of the driving wheels . It also send power to the generator which recharge the electric motor battery . in return the electric motor gives the driver more power and torque while reducing fuel consumption . in The hybrid system , when the car in breaking or coming to stop the system keep it’s kinetic energy from the turning wheels and the breaks , it confer that into electrical energy and store it into the battery where it can be used in the future .

Start – Stop Engine

Start – stop engine will shut off the car when the car is fully stopped , so when coming to complete stop in traffic and remove your foot from the break the car is going to shut off to save on emtition  and fuel. As soon as the driver takes his foot up the break the car starts right back up and can continue driving

CVT (Continuously Variable Transmissions )

CVT is a method of transferring power from an engine , which maybe  used in consumption  engine or an electric motor . In case of electrical motor , these are usually controlled electronically and so CVT is more benefit when it is used with consumption engine as a method of transferring power to the driven component.The main advantages of CVT are providing a comfortable  driving and saving up to 7% of fuel consumption.

Genetically Modified Crops

We came to a place where the technology revelation takes over almost everything in our life today, and a good example for that is GMO “ genetically modified food “ .

Genetic engineering is a process where scientists take genes from species and force it to DNA of other species. Today genetically modified food have invaded the America food supply, almost 90 % of crops like corn and soy are now genetically modified . The reason for that big percentage is that genetic engineering promises to increase crops yield, low cost for farmers, and reduce the use of Herbicides .

The question is are we really achieving these goals?

 

Some of GMO’s supporters say that genetic engineering is a safe and beneficial process, and they are saying it is an extinction of natural plant propagation. In fact genetic engineering is a laboratory based technique where a foreign gene is inserted into DNA of the plant. This is an uncontrolled process, because the site of insertion is random and my potentially damage the plant’s genetic makeup. The mutation that occur during the process can lead to unexpected changes in the resulting crops such as: poor crop performance, alteration in the food’s nutritional content, toxic and allergenic effects.

 

Some GMO’s promoters claim that genetic engineering reduce pesticide use . In fact it does not , it leads to an increase in the amount of pesticide and herbicide used . Also, they say it increases the corps yield potential, but it actually has opposite effect of glyphosate eyelets soil quality by killing the natural nutrients and organisms that necessary of the plants development leading to plant diseases . Glyphosate is highly Invasive and can mix with rain , air ,soil and  water ground .

 

Genetically modified crops are as energy –hungry as any other chemically farmed crops . GOM’s crops consume massive amount of energy, because they are depending on Herbicides with use fossil fuel during manufacturing . GOM are also depending on nitrogen fertilized which emit green house gas .

 

GMO’s promoters say that the main goal of genetic modified crops  is to help to eliminate the world hunger and protect the security of food supply. In fact there are no genetically modified crops that increase intrinsic yield, and the world hunger is an issue of allocation of resources .

 

There are no conclusive safety studies on GOM , most regulatory assessment on GMO are only based on the data provided by biotech companies applying to commercialized GMO crops and these are the same companies that profit from the positive assessment . The U.S FDA does not have a safety assessment process for GMO , also independent researchers are prohibited from using genetically modified food for their studies and if they found a problem with the GMO their work will be called “flawed insubstantial “ . Over 50 countries all over the world have now passed GMO  labeling laws and GMO crops restriction in order to insure people health . On the other hand Canada and U.S.A  still have not come to this step and there is no justification for that .

 

In conclusion, genetically modified crops is a good step to improve our lives and food sources ,but it needs to be put under a lot of studies and reaches in order to get the optimum benefits for it and to avoid any kind of harm it may cause.
