* Coal swaps trade near 4-year lows
* Price falls in line with lower oil, gas and power markets
LONDON, April 2 (Reuters) - European coal futures contracts hovered close to four-year lows of just above $80 per tonne on Wednesday afternoon as the entire energy sector saw prices fall.
API2 2015 coal futures contracts were trading at $80.05 per tonne at 1625 GMT, similar levels seen during the height of the global financial crisis in 2008 and 40 percent below last peaking in 2011.
Coal prices have steadily dropped during the past three years, suffering from weakening demand in both industrialised and emerging economies, and because exports are increasing in most producing counttries, such as Australia, Colombia, South Africa and the United States.
Wednesday's downward move was further supported by falling prices across energy markets, traders said.
"The entire energy sector - oil, power, gas and coal - saw some pretty substantial drops today, so coal was just swimming along with the tide," one energy trader said.
In oil markets, Brent crude fell more than $1 to a near five-month low near $104 a barrel on Wednesday with expectations that rebel-held Libyan ports would reopen within days outweighing an unexpected drop in U.S. crude inventories.
In natural gas, British benchmark prices hit near two-and-a-half-year lows as warm weather reduced demand, leaving the system oversupplied.
In Europe's power markets, German prices for next year fell to 33.85 euros ($47) per megawatt hour as weak demand continued to clash with overcapacity.
