How to Reduce Global Warming

Global warming is the name given by scientists for the gradual increase in temperature of the Earth’s surface that has worsened since the industrial revolution.

According to carbon footprint, over the past two decades the effect has become more marked. Considerable evidence exists that most of this warming has been caused by human activities…that’s to say we have altered the chemical composition of the atmosphere through a buildup of greenhouse gases – primarily carbon dioxide, methane, and nitrous oxide.

What if we do nothing?

Rising global temperatures will cause sea level to rise and alter local climate conditions, affecting forests, crop yields, and water supplies. It may also affect human health, animals, and many types of ecosystems. Deserts may expand and some of our countryside may be permanently altered.

What will happen in the future if we do nothing?

Climate model stimulations predict an increase in average surface air temperature of about 2.5 degree C by the 2100.

The likelihood of “killer” heat waves during the warm season will increase (Karl et al., 1997)

The IPCC second Assessment Report estimates that sea-levels will rise by approximately 49 cm over the next 100 years, with a range of uncertainty of 20-86 cm.

Reducing Your Carbon Emissions

Action for climate change supports the following list of actions you can easily undertake for little or no cost and significantly reduce your greenhouse gas emissions.

According to actionforclimatechange.org, the actions are listed in priority order – addressing the areas where households generate the majority of the greenhouse gas emissions.

Travel:

Cars are the highest source of greenhouse gases from households and account for 34% of the total emissions. To reduce your greenhouse gas emission, aim to leave your car at home once a week.

Water heating:

Hot water is the second highest source of greenhouse gases generated by households.

There are many things you can do for free to decrease your greenhouse gas emissions, these include: wash your clothes with cold water. Cut your bill by using only the cold cycle on your washing machine. Compared to a hot wash, this will save four kilograms of greenhouse gas per wash.

Take shorter showers. Keep your showers to four minutes; you will save up to half a kilogram of greenhouse gas for every minute.

Lower thermostat:

Most hot water systems came with a thermostat and you can get an electrician or plumber to vary the set temperature.

Electric Car Conversion - Batteries

Batteries are indispensable to electric car conversion ; some regard it as the heart of the whole process. I cannot help but agree with them totally. For this fact, the need for special kind of battery called deep cycle battery cannot be comprise. This kind of battery ensures that your electric car work properly. Deep cycle battery is simply amazing, its ability to charge quickly and discharge further then regular car batteries normally found in your vehicle now. Pic-Batteries? This system in the deep cycle battery, picture it as water pouring out of a glass. Every day battery can only pour about $10 of the water out; on the other hand, deep cycle battery can pour or discharge down 30% or so. Do not go down lower than 30% though, topping up a battery that is to the 70% level is as low as you go. What can l get deep cycle batteries? Having lived off the grid for over 10 years now and have been living with battery systems to run our home for that long. The batteries used in wi...

Applications Of Deep Cycle Batteries

Storage batteries are these days used for a great variety and range of purposes, some of which are below. 1.    In central stations for supplying the whole load during light load periods, also to assists the generating plant during peak load periods, for providing reserve emergency supply during periods of plant breakdown and finally, to store energy at times when load is light for use at time when load is at its peak value. If you cannot wait to start YOUR OWN ELECTRIC CONVERSION: I employ you to Click Here NOW! 2.    In private generating plants both industrial and domestic use, for much the same purpose as in central stations. 3.    In sub-stations, they assist in maintaining the declared voltage by meeting a part of the demand and so reducing the load on and the voltage drop in, the feeder during peak-load periods.

Focus On Adaptors And Chargers

The adaptor plate attaches the electric motor to the formal manual transmission and clutch. Adaptors are precision machined ready from for install, once it is ordered. If you cannot wait to start YOUR OWN ELECTRIC CONVERSION: I employ you to Click Here NOW! The adaptor is comprises of four different parts, the transmission profile plate made from aluminium, and mimics which provides the main mounting surface. Another type is the motor spacer ring made of aluminium; it attaches to profile plate and recreates the formal spacing between the flywheel and transmission. Having acquired good deep cycle batteries, the charging system is worth to be given all attention to, so as not to shorten the life span of the batteries. Early version of charges only forced voltage in the batteries until turn off by the owner. This action will cause the battery bank to gas toward the end of the charging process, and shortened its life span. In what seem like advancement in battery charging system,...
