Floor Speeches: In Opposition (17) AI
Argued the budget does nothing to address energy affordability despite 1.3 million residents behind on utility bills. Criticized the failure to return $2.4 billion in unspent Clean Energy Fund money to ratepayers and questioned the CLCPA's impact on utility costs.
Called the bill dysfunctional government, noting cannabis is a gateway drug and the black market remains rampant. Criticized that revenue from cannabis sales is being used for drug rehabilitation facilities.
Argued the bill is an unfunded mandate that will increase utility bills and drive residents out of New York. Questioned the cost data supporting savings claims and cited PSC reports showing 10 percent rate increases since CLCPA inception. Expressed concern about job losses for gas utility workers and plumbers without adequate retraining provisions.
The bill denies New Yorkers freedom to choose their energy source. Polls show 71 percent of New Yorkers oppose banning natural gas and 59 percent oppose pipeline bans. The state should support pipeline expansion and LNG infrastructure rather than unrealistic bans that harm ratepayers and businesses.
Voted in opposition to the measure.
