Is solar technology going to rescue us?
Have we really past peak oil?
Could solar technology solve our future problems.
Mans most pressing problem is climate change.
Will climate change alter if we use solar technology?.
Who uses the Sahara Desert to capture and store carbons?
Can we alter our changing world by planting trees or is mother earth broken forever?
Can new technology turn back the clock on global warming, help us cap our global emissions and save us from a rapidly warming planet?
Our modern life is built on petroleum energy, we use energy to heat, cool, light up our cities, power our cars, fly our planes, fill our shop shelves, harvest our food, keeps us switched on and plugged in.
In the average homes in the 1980s there were 3 electronic devices, today there are over 25, most of the required energy comes from burning coal oil or gas.
Most people do not understand when they switch on a light switch where that energy source comes from.
Is there a better way, earth needs a miracle in energy technology, maybe the answer is solar system
radiation technology, solar technology.
Scientists in laboratories including other professions around the world are racing against the clock to find energy solutions tapping the power from our sun harnessing its intense useful resource. People thought fuel was going to change the world, well it has, we need solutions innovating faster, maybe re-examine nuclear power ultimately the question is can solar technology systems save us from climate change, greenhouse gasses?
What is peak oil? World oil reserves become a highly prized commodity.
Whatever you read about peak oil humans appear very near a major intersection crash of less oil, much higher and increasing oil prices. Wayback 50 -300 million years ago nobody knows for sure fossil fuels began forming
since then world consumption running at 85 million barrels per day has burnt more than half of known oil reserves in 120 years. Assuming peak oil exists our lifestyles are possibly going to become more basic, should this scenario eventuate will solar technology stepup to the challenge?.
Can solartechnology help us fuel our future?
How can we get the energy our world needs in a way that will not threaten us or our planet?
Deep in a West Virginia Coal Mine which generates half of all the US electricity tells a story millions of years old. Thirty five million years ago earths atmosphere was awash with carbon dioxide, alligators swam in North Dakota, palm trees in the Rocky Mountains and instead of being covered by ice there were forests in Antarctica. Over millions of years those trees extracted the carbon from the air to grow, when they died much of that carbon got buried under ground, this main process created the coal we see in West Virginia. Coal is up to 86% carbon, 4.5 litres of petrol which is a fossil fuel represents nearly 100 tons of ancient plant, thats why coal gas and oil are called fossil fuels. With the advent of the industrial age carbon rich fuel was extracted and burnt as fuel. Burning anything releases carbon but carbon dense coal and oil means a lot more. Carbon long buried combines with oxygen in the earths atmosphere and acts like a blanket trapping heat. This mass amount demonstrates global temperatures rising throughout last century. Nobody knows precisely where temperatures will rise or how quickly, predictably atmosphere carbon by century end will approach levels encountered 35000 million years ago when those alligators swam in North Dakota.
The path ahead is cutting carbon emissions drastically.
Carbon reductions can be grouped into six simple categories.
1. Efficiency, (you get the same bang for less dollars)
Cars which are far more fuel efficient offering better kilometres per litre.
e.g. Carbon capture, US Navy has relied on this theory for decades using a
2 Improving motor vehicle economy from 50 -100 kilometers per 4.5 litres
3 Houses which do not leak heat; e.g. Thermal imaging cameras can expose heat
loss, efficient heaters, utilize lights which burn brighter consuming 20% less power .
A. Identify energy losses from the home. Increase your home efficiency.
4. Utilizing aggressive tidal currents harnessing wave energy.
5. Tripling the number of nuclear power plants over the next 50 years.
6. Replanting significant sustainable forests where trees are re-used for useful purposes such as
houses, buildings, furniture.
Nuclear power could replace 800 coal plants but would have to be safer that that of the recent disaster in Japan. They require massive cooling systems keeping the reactor core cool - newly designed reactors have large cooling tanks sitting right on top letting gravity takes its course rather than cooling flowing through pipes. Tanks have a three-day cool water supply requiring no electricity. This next generation of nuclear plant is already in China - the AP1000 which is made up of 330 modules which are moved into place with the reactor cooler generating enough power for a million homes.
Cleaning up coal plants by burying their carbon emissions, sounds great but can we do it?
Our modern world has an insatiable appetite for energy, directly linked to economic growth and prosperity. Currently fossil fuels feed 85% of energy demand. Coal is critical not just because 50% of electricity comes from coal in the United States but 80% of electricity China uses comes from coal.
The process of capturing and burying carbon from Natural Gas Plants is already being effectively trapped back underground on a massive scale already in a place where people do not take taxis they use camels, the Sahara Desert, which may be an important link to our planets future.
There are only four such large facilities operating on a large scale in the world that bury carbon under ground, there is no commercial reason for it. If the price of fossil fuel reflected the damaged caused by green house gases then there would all of a sudden be an economic reason to store the carbon dioxide below the ground.
Average family carbon foot print.
Heating our homes driving our cars growing and shipping our food creates an average family carbon footprint per annum of 14 tons carbon waste, which combines in the atmosphere with oxygen creating 50 tons of carbon dioxide gas. That gas floating in the atmosphere lets sunlight enter to warm earth but blocks much of the heat from escaping, its like an invisible vortex blanket warming our earth.
Which is the best way we use energy with the least carbon emissions?????
There are many possible technology solutions it just depends on our choices.
1 The Sun; solar power electricity, harnessing its powers with solar electricity panels,
solar hot water collectors, wind turbines.
2 Wind power is non-polluting with outstanding potential.
3 Harnessing wave energy and off shore winds to use earths geothermal sheet.
4 Solar power nz solar technology is clean energy.
5 Today if we are to take climate change seriously nuclear power should also be
One Nuclear power plant is as big as a 3000 wind turbines the question is
which one do you want in your back yard ??
6 Plant more useful types of trees.
Problem is a moving target, every day as demand grows the carbon accumulates
in the atmosphere, problem is procrastination has penalties.
Energy demand appears unstoppable in fact energy demand is predicted to triple before century end which means there is probably a need for every solution people can think of.
Efficiency saves you money it doesnt cost you money, tools are available to fight climate change.
