In countries where electricity provision is deregulated, end-users of electricity may opt for more costly "green" power.
All forms of electricity generation have positive and negative aspects. Society will eventually declare a winner, but in a free-market economy, the option with less overall costs generally will be chosen above other sources. It is not clear yet which form can best meet the necessary energy demands or which process can best solve the demand for electricity. There are indications that renewable energy and distributed generation are becoming more viable in economic terms.
