The full life cycle emissions-equivalence impacts of solar/wind are much lower than any fossil source, so reminding people of the embodied energy feels more diversionary than informative. The IPCC's 2014 median estimates indicated that the heaviest-lifecycle renewable source (utility scale solar PV) has only 9.8% of the impact of the lightest fossil source (combined cycle gas turbine). Onshore wind power has only 2.2% of the impact. (For comparison with coal the numbers are respectively 5.8% and 1.3%)
