(CNN)  -- There was no mistaking the target: the eight huge cooling towers at Ratcliffe-on-Soar power station, sending plumes of steam high into the watery blue sky of the English Midlands.



A mix of peaceful protest and direct action took place at Ratcliffe-on-Soar, England.



Instead the question in the minds of an estimated 1,000 protestors gathered in the surrounding woods and scrubland was how could they get in and shut it down.



Surrounded by electrified fences, coils of razor wire and hundreds of police, this coal-fired power station run by German energy firm E.On was the target of environmental activists campaigning to stop climate change.



Organizers of the protest, an amorphous group called the Camp for Climate Action, claim the plant is one of the UK's largest sources of CO2 emissions and had named last weekend's protest, "The Great Climate Swoop".



"Climate change is one of the most important and urgent problems facing us," one protestor called Emma, told CNN. "Our politicians are not doing enough. We have to take action."



"We need to increase the pressure on [UK prime minister] Gordon Brown until he changes his mind about coal," said another called Magoo. "I wouldn't be here if I thought we couldn't make a difference today."



Many protestors were upbeat following a recent decision by E.On to shelve plans for a new coal powered power station at Kingsnorth, in southern England, and the site of a similar protest in 2008. E.On told CNN that the decision was "purely economic", and "due to a marked fall in demand for electricity during the recession", although many activists were claiming it as a victory for them.



Determination to act



There was no doubting the activists' dedication. The weekend began peacefully enough with a procession snaking up from the East Midlands Parkway train station accompanied by a pedal-powered sound-system and a band. Several officers told CNN they were glad to be policing this event rather than a local football derby on the same day.



Yet over 24-hours police say 57 protestors were arrested and both police and activists were injured in violent scuffles.



The protest at Ratcliffe-on-Soar was the latest from a movement that has quickly come to define environmental activism in Britain, mixing elements of the mid-1990s road protest movement with the more targeted, professional approach of groups like Greenpeace and the mass civil disobedience modeled by the Campaign for Nuclear Disarmament.



Although leaderless and non-hierarchical it has shown determination, organization and direction. There were several families with young children at the protests, as well as individuals of all ages, although the bulk were twenty- and thirty-somethings.



While some wore bandanas to hide their faces, others were in dressed as clowns or scarecrows and seemed content to picnic within sight of the plant.



Peaceful protest and police



In the spring James Hansen a climate modeler for NASA and prominent scientist lent his support for direct action, telling The Guardian newspaper: "The democratic process doesn't quite seem to be working... I think that peaceful demonstration is not out of order, because we're running out of time."



The first action by Climate Camp for Climate Action was at Drax coal power station in 2006, followed by Heathrow airport in 2007 and Kingsnorth coal power station in 2008. In 2009 there have already been three events: a protest at the European Climate Exchange in London, to coincide with the G20; a camp on Blackheath, London, in August -- the site of the 1381 Peasant's Revolt - and now the protests at Ratcliffe.



All have been characterized by a mix of peaceful protest around a "camp" that is intended to model low-carbon living, alongside militant direct action - and an increasingly tense relationship with police.



At Kingsnorth a huge police presence carried out over 8,000 searches according to an official report by the National Policing Improvement Agency, which also criticized tactics as "disproportionate and counterproductive".
