We need to develop some alternative energy sources quickly
In the past, electricity has usually been generated used fossil fuels such as coal but unfortunately these resources are finite and supplies have almost run out. In addition, their use has damaged the environment due to the large amount of carbon dioxide these generation methods produce and this contributes to the greenhouse effect and causes global warming.
We need to find some alternative energy sources quickly.
Possible sources of alternative energy include solar power, wind power, energy from the sea and biomass although there is no doubt that other possibilities exist and may become significant
Fossil fuels are so called because they were formed from the remains of prehistoric plants and animals.
Examples of fossil fuels include coal, oil and gas and they provide approximately 95% of the worlds energy needs.
When used to produce electricity coal is crushed then burned, used to heat water, the steam produced is used to turn turbines, the turbines turn generators and this generates electricity. Burning coal produces sulphur dioxide which causes acid rain. It also produces carbon dioxide which is the cause of the greenhouse effect and global warming.
Coal and other fossil fuels are finite resources and have almost run out. They will not last much longer.
We need to develop some alternative energy sources quickly
One possibility is nuclear power which produces approximately 11% of the worlds energy needs.
Nuclear fission is used to split uranium atoms and this produces energy in the form of heat.
This is used to heat water, the steam produced is used to turn turbines, the turbines turn generators which generate electricity.
It is not expensive, very reliable, very efficient and does not cause acid rain or global warming.
However, the small amount of waste produced is extremely dangerous and must be supervised and controlled for thousands of years. It must be protected from natural disasters and any other threats and the processes involved will be difficult and expensive.
If anything goes wrong, a major disaster will occur affecting millions of people e.g. Chernobyl.
Do we really want to leave such a legacy for our children?
During the next century, fuel will become increasingly scarce.
We will need to generate electricity to keep the lights on and keep our computers running.
Maybe we have no choice.

Rugby League
This article discusses a sport that many of you will be unfamiliar with. It is popular around the world but those from the United States are unlikely to have heard of it although the USA does have a national team.
History
Rugby League is a very popular spectator sport in England, Australia and New Zealand but is also played in many other nations. It is very similar to Rugby Union. In fact, the rules of Rugby League were created in 19th Century England as a split from the Rugby Football Union. Unlike in American Football, players do not wear protective gear and consequently rugby league is a highly dangerous game. This also makes it great fun to watch.
Rules
Competitions
Aside from the rugby league world cup, the rugby league four nations is probably the most famous international tournament.

Unlike in American Football, players do not wear protective gear and consequently rugby league is a highly dangerous game. This also makes it great fun to watch.
Rules
The aim of the game is to get the ball past the other side's goal line (similar to a touchdown zone in American Football). Instead of a touchdown this is called a try and is worth 4 points. 2 points are awarded if a goal is scored and after scoring a try, the team has the chance to convert a goal. Goals can also be scored in the normal run of play by half volleying the ball between the goal bars. Each game lasts for 80 minutes and each team has 6 tackles or downs to aim to score a try. Unlike in American Football, players can only pass backwards not forwards. Only the player holding the ball is allowed to be tackled by the defending team. If the ball is dropped onto the ground by the attacking team then play immediately switches known as a handover and the defending team gets to attack. Not only do fans like to watch the games but some punters also enjoy rugby league betting.
Competitions
Aside from the rugby league world cup, the rugby league four nations is probably the most famous international tournament.
Four Nations betting fever takes over Australia during the tournament. In 2011 the four teams competing will be Australia, England, New Zealand and Wales. Notable domestic competitions include the European Super League for club teams and the Austalian NRL. Article Source: http://ezinearticles.com/?expert=Harry_Samson |

Alternative Energy - If This Were Any Other Sector of Our Economy - We'd Call It a Bubble!
The Alternative Energy Industry is an industry - don't let anyone tell you otherwise, and it's a 10-trillion dollar industry for new equipment and power plants. In fact, if you count the commodity trading sector of energy along with "carbon credit" trading of air it could be a 50-trillion dollar industry by the end of the decade. On November 29, 2010 there was a whole section in the Wall Street Journal dedicated to it - a whole section! And realize the WSJ is not a left-leaning socialist newspaper, rather it's all about money flows and markets.
Alternative Energy is an Industry.
Indeed, Alternative Energy is the fastest growing industry in the world. This is what has been created using propaganda, guilt trips on the populations, and careful promotion amongst the media to the masses. A good portion of the public now treats Global Warming as a religion with the fervor and passion of a new found God. And the already zealous environmentalists have joined the cause with all their sound and fury, as trumpet blowers at every turn.
However, Alternative Energy is still an industry, so let's not kid ourselves.
It is an industry that's been pumped up by media, big money, big oil, environmentalists, government funding, and your favorite billionaires around the globe, and they all intend on cashing in on it. Will building this bubble save us from the collapse of the last one? Do bubbles ever save us, or do they just make things worse down the road when the big boys walk away with the loot.
Folks, it's too late to stop it now, they are huffing and puffing and blowing this bubble up to kingdom come. We are all just along for the ride now with higher taxes to pay for subsidies and higher energy costs to make it work. But it won't, it can't - whenever our energy costs go up we lose jobs, our economy sputters, and there you have the reality. Consider the high oil costs of the past which always preceded economic downward spins of the business cycle.
Today, we have everyone running for the money, getting there any way they can - looking for research grants, incentives, tax breaks, start-up loans, venture capital, or even jobs. Indeed, we already see cracks in the wall, we have alternative energy projects which have failed, venture capital firms pulling money aside, and start-ups with a promise, a great business plan, and a fast talking entrepreneur, but no chance in "hello" of ever making a return on investment.
I presume that is how this larger balloon will go, and how this cookie will crumble.
Please consider all this.
