Millions of households across America are taking a first step into the world of the "smart grid," as their power companies install meters that can tell them how much electricity they are using hour by hour -- and sometimes, appliance by appliance. But not everyone is happy about it.

Customers in California are in open revolt, and officials in Connecticut and Texas are questioning whether the rush to install meters benefits the public.

Some consumers argue that the meters are logging far more kilowatt hours than they believe they are using. And many find it unfair that they will begin to pay immediately for the new meters through higher rates, when the promised savings could be years away.

The European Union reached agreement on Monday to put an end to a decades-long trade dispute with Latin American and other smaller producers over tariffs on banana imports, diplomats said.

"Everybody is finally on board and an initialling of the deal is scheduled for Tuesday," one diplomat with direct knowledge of the negotiations told Reuters.

The deal resolves the world's longest-running trade dispute, which involves banana exporters in Latin America and other regions challenging the EU's preferential treatment of producers in the Africa, Caribbean and Pacific region.

As global leaders and top scientists in Copenhagen debate how to deal with climate change, farmers in flood-prone areas of northern India are taking it into their own hands to adapt to shifts in the weather.

For decades, people of Uttar Pradesh, whose population is more than half that of the United States, have been witnessing erratic weather, including increasingly intense rainfall over short periods of time.

The rain, combined with heavy mountain run-off from nearby Nepal, which is also seeing heavier-than-usual rains, has inundated villages, towns and cities in the region.

An octopus and its coconut-carrying antics have surprised scientists.

Underwater footage reveals that the creatures scoop up halved coconut shells before scampering away with them so they can later use them as shelters.

Writing in the journal Current Biology, the team says it is the first example of tool use in octopuses.

One of the researchers, Dr Julian Finn from Australia's Museum Victoria, told BBC News: "I almost drowned laughing when I saw this the first time."

EL ALTO, Bolivia -- When the tap across from her mud-walled home dried up in September, Celia Cruz stopped making soups and scaled back washing for her family of five. She began daily pilgrimages to better-off neighborhoods, hoping to find water there.

Though she has lived here for a decade and her husband, a construction worker, makes a decent wage, money cannot buy water.

"I'm thinking of moving back to the countryside; what else can I do?" said Ms. Cruz, 33, wearing traditional braids and a long tiered skirt as she surveyed a courtyard dotted with piglets, bags of potatoes and an ancient red Datsun. "Two years ago this was never a problem. But if there's not water, you can't live."

The glaciers that have long provided water and electricity to this part of Bolivia are melting and disappearing, victims of global warming, most scientists say.

If the water problems are not solved, El Alto, a poor sister city of La Paz, could perhaps be the first large urban casualty of climate change. A World Bank report concluded last year that climate change would eliminate many glaciers in the Andes within 20 years, threatening the existence of nearly 100 million people.
