Climate skeptic scientists have long questioned whether the effects of relatively minor (compared to other CO2 sources and sinks) human - caused emissions of CO2 have more than a minor effect on global temperatures and some have even questioned whether the UN and USEPA have even gotten the causation backwards (i.e., because on balance global temperatures affect atmospheric CO2 levels).

For the avoidance of doubt, Gross Revenues shall (A) exclude monies received from any source other than the sale of electric energy and capacity, including, without limitation, any of the following: (i) any federal, state, county or local tax benefits, grants or credits or allowances related to, derived from, or granted to the Wind Energy Project or Grantee, including, but not limited to, investment or production tax credits, or property or sales tax exemptions, (ii) proceeds from financing activities, sales, assignments, partial assignments, contracts (other than the power purchase agreement) or other dispositions of or related to the Wind Energy Project (such as damages for breach of contract or liquidated damages for delays in project completion or failures in equipment performance), (iii) amounts received as reimbursements or compensation for wheeling costs or other electricity transmission or delivery costs, and (iv) any proceeds received by Grantee as a result of damage or casualty to the Wind Energy Project, or any portion thereof and (B) include any revenues derived from Grantee's sale of carbon dioxide trading credits, renewable energy credits or certificates, emissions reduction credits, emissions allowances, green tags, tradable renewable credits, or Green - e ® products, any of which are allocated to Grantee, if applicable, through its participation in any voluntary registry, association or market - based exchange.
