BBC - GCSE Bitesize - Energy

All life on earth is sustained by energy from the sun. Plants and animals can store energy. Some of this energy remains with them when they die. It is the remains of the stored-up energy of ancient animals and plants that make up the fossil fuels that power our cars and factories today.But fossil fuels are non-renewable energy sources and will one day run-out and because burning them generates greenhouse gases, relying on fossil fuels for energy generation is unsustainable. Hence the need to find more renewable, sustainable ways of generating energy.

Energy Resources: Fossil Fuels

What do I need to know?

"Energy Resources" is NOT the same thing as "Types of energy".

"Types of energy" means "kinetic energy", "chemical energy" and so forth.

"Energy Resources" is about ways of getting energy so we can generate electrical power.

BBC NEWS | World | Africa | Life dries up in Kenya's Mau forest

 

High in the hills of Kenya's Mau forest, some 20,000 families are facing eviction from their farms - accused of contributing to an ecological disaster which has crippled the country.

THE HEART OF KENYA

Mau forest is the largest in Kenya - the size of the Aberdares and Mount Kenya combined

10 million people depend on its rivers

They feed six lakes - Victoria, Turkana, Natron, Nakuru, Baringo and Magadi

Plus eight wildlife reserves - including the Masai Mara, the Serengeti and Lake Nakuru

The rivers have potential for 518MW hydro electricity - 41% of Kenya's total

In all, the forest provides an economic benefit of 20 billion shillings (£166m) per year (UNEP)

But already, a quarter of its 400,000 hectares have been destroyed by farmers and loggers

Can China help to defuse the nuclear threat from Iran?

As a veto-holding permanent member of the UN Security Council, China's position will be crucial to international efforts to deal with Iran's secret nuclear facility.

"Iran is an important country for China: we have diplomatic interests, but also energy and trade links," he said. "[And] if China is too harsh, it will not be favourable to its image and influence in the Middle East."

China is the world's second-largest consumer of crude oil while Iran has the world's second largest reserves; Iranian oil made up more than a tenth of China's crude imports last year. Earlier this year, the two countries announced a $3.2bn three-year natural gas deal, and in the spring Iran's Press TV reported that trade volume between the countries leapt from $400m in 1994 to $29bn in 2008.

Iran and United States on collision course over nuclear plant | World news | The Observer

The US and Iran raised the stakes yesterday ahead of this week's nuclear showdown in Geneva, with threats of global strife if no resolution is found.

The sharpened rhetoric followed Friday's revelation that Iran had been building a secret uranium enrichment plant under a mountain near Qom, and it points towards a new wave of sanctions that go far beyond the targeted financial measures imposed on Iran so far.

Speaking at the G20 summit in Pittsburgh, Barack Obama declared: "Iran is on notice that when we meet with them on 1 October they are going to have to come clean, and they will have to make a choice." The alternative to sticking to international rules on Iran's nuclear development, he said, would be "a path that is going to lead to confrontation".

10:10 | What is 10:10?

10:10 is an ambitious project to unite every sector of British society behind one simple idea: that by working together we can achieve a 10% cut in the UK’s carbon emissions in 2010.

Why bother jumping out of the way of a speeding car? Why bother removing a burst appendix?

Cutting 10% in one year is a bold target, but for most of us it’s an achievable one, and is in line with what scientists say we need over the next 18 months. We now know for certain that unless we act quickly to reduce our use of dirty fossil fuels, humanity will face terrible problems in the years to come. Politicians have so far failed to do what needs to be done, so it’s time for ordinary people to step in and show that we’re ready to defend our children’s futures. It’s now or never for the climate.

Kenya's slums attract poverty tourism

Tourists snapping up £20 guided walks around Nairobi's open-sewer streets

The Dutch tourists came well prepared for the walking safari: strong shoes and sunscreen, backpacks and bottled water. Ahead lay an afternoon visiting one of Kenya's most recognisable sights – but one that rarely features in tourist brochures.

"It might seem a bit strange to come here," said Eric Schlangen, as the guide led him towards the sea of tin-roofed shacks that constitute Kibera, often described as one of the world's largest slums. "But I wanted to see how people live in this country, not just the animals."

Slum tourism is taking off in Kenya. Several local organisations have started selling guided trips through Kibera, a short drive from the luxury hotels that serve most foreign visitors in Nairobi.

For about £20, tourists are promised a glimpse into the lives of the hundreds of thousands of people crammed into tiny rooms along dirt paths littered with excrement-filled plastic bags known as "flying toilets", as one tour agency explains on its website.

New surfers' reef fails to make waves

In the parlance of the surfing community it was supposed to attract, Bournemouth's new £3m underwater reef was meant to be Gnarlatious, creating giant Honkers from Atlantic swells and so bringing in legions of Dudes and Dudettes who flock to resorts in Cornwall and Devon each year to ride Bamboras.Instead it has turned out to be Bogus, and is making waves for all the wrong reasons.As work on the reef at Boscombe comes to a close, surfers say there is still no sign of the promised "world-class" waves it was meant to create. Residents are furious that the project, which is more than a year behind schedule and has cost three times the original budget, is failing to deliver.

Ozone Hole Appears On the Mend

Satellite instruments monitor the ozone layer, then the data are used to create images that depict the amount of stratospheric ozone. The blue and purple colors are where there is the least ozone, and the greens, yellows, and reds are where there is more ozone.The size of the hole in stratospheric ozone that develops over Antarctica at this time each year appears to have stabilized, according to satellite observations analyzed by various agencies around the world. Matthew Tulley from Australia’s Bureau of Meteorology says the hole has begun to show signs of healing because of the international agreement to phase out the production of ozone-depleting chemicals in the 1987 Montreal Protocol. Recent observations indicate that the level of ozone-depleting substances has decreased by 4 percent since 2001.

Rash of Water Main Breaks Points To Vulnerability of Systems

 

Recent water main breaks highlight challenges to water infrastructure.Major water main breaks in Los Angeles and Baltimore in recent days highlight challenges to the U.S. water infrastructure system.

A rash of water main breaks in the Los Angeles water system this month have flooded streets, forced residents to evacuate, and damaged homes and businesses, the Los Angeles Times reported. One break created a sinkhole that nearly swallowed a firetruck responding to the scene, while another sent a surge of mud and water 10 feet into the air.

Since the start of September, L.A.’s Department of Water and Power has recorded 34 “major blowouts” in the city’s water system, the Los Angeles Times reported Sept. 19. By contrast, the city had only 21 such ruptures through all of September 2008, 17 in September 2007 and 13 in September 2006.

Storm chaser

The extreme weather photographer and storm chaser Jim Reed has spent the past 20 years as close as possible – perhaps closer than is advisable – to the most extreme meteorological events. Covering disasters such as Hurricane Katrina and Hurricane Ike, Reed's book, Storm Chaser: A Photographer's Journey, documents his time in the field.
Surviving the direct strike of 17 hurricanes in the US, 2010 marks Reed's 19th consecutive year of extreme weather photography. Reed currently has images being shown at the Corcoran Gallery of Art in Washington

How to measure an earthquake

 

Originally, Charles Richter used information from seismographs - which measure earth movement - to work out the location and size of a tremor.

He developed a sliding scale based on the distance between an earthquake and the seismograph station where the quake was recorded and the amplitude of the largest seismic wave measured.

Aral Sea Continues to Shrink, August 2009 : Image of the Day

 

Throughout the first half of the twentieth century, the Aral Sea was the world’s fourth-largest lake. In the 1960s, the Soviet Union began a massive irrigation project in what are now Kazakhstan, Uzbekistan, and Turkmenistan, diverting water from the rivers that feed the Aral Sea to irrigate farmland. As its water levels dropped, the lake began splitting into smaller pieces: the Northern (Small) Aral Sea and the Southern (Large) Aral Sea. The Southern Aral Sea further split into eastern and western lobes. The Earth Observatory’s World of Change: Evaporation of the Aral Sea feature tracks this process over the past decade.

A vision of Britain in 2020: power cuts and the 3-day week

Britain's homes could be without light and heat for long periods by 2020 with the government being forced to repeat the 1974 imposition of power cuts by rota, a doom-laden report by the Institution of Civil Engineers (ICE) says today.

By then, 80% of the gas to fuel Britain's power stations and domestic central heating will be piped "from politically unstable countries thousands of miles away." Mechanical failure, sabotage and terrorist attack would lead to power cuts within days, the report says. The society, established in 1818, says Britain will be at the end of a pipeline which passes through several other countries relying on imported gas.

Population growth at 47-year high

The UK population grew by 408,000 in 2008 - the biggest increase for almost 50 years, according to the Office for National Statistics.

The total number of people passed 61m for the first time, with changes in birth and death rates now a bigger cause of growth than immigration.

The numbers of people arriving minus those leaving actually fell by 44%.

Shanghai urges 'two-child policy'

 

China's only children are often spoiled "little emperors"

Officials in Shanghai are urging parents to have a second child, the first time in decades the government has pushed for more babies.

A public information campaign has been launched to highlight exemptions to the country's one-child policy.

Couples who were both only children, which includes most of the city's newly-weds, are allowed a second child.

The move comes as China's most populous city becomes richer and older, with the number of retired residents soaring.

"Shanghai's over-60 population already exceeds three million, or 21.6% of registered residents," said Zhang Meixin, a spokesman for the city's Municipal Population and Family Planning Commission.

The belief that local is best when it comes to measuring the environmental impact of our food is often wrong, says new research

 

Millions of Britons who think they are doing their bit for the environment by choosing home-grown food over produce imported from thousands of miles away could actually be having the reverse effect, according to a startling new report.

The "food miles" philosophy that decrees anything transported over distance is worse for the environment than something closer to home is frequently flawed, according to researchers funded by the Department for Environment, Food and Rural Affairs (Defra).
