7.2.6—Energy conservation and efficiency question 1
[Maximum number: 3]
Suggest three different strategies that may be used to manage global energy consumption.
increase production of energy from renewable resources/ wind /solar/tidal/nuclear;
increase efficiency of energy usage through technological development; increase awareness of energy-saving practice through education/campaigns; address issues of energy distribution through import/export; promote exploitation of locally appropriate/available energy sources to reduce need for import/export; seek new reserves of non-renewable energy resources/fossil fuels; provide technical support/economic subsidy for renewable/clean/efficient energy supply;
imposing legislated caps/taxes/limitations to energy consumption/C production; anti-natalist policies reduce population growth and energy consumption; reducing energy consumption through recycling/reusing resources (recycling uses energy but less);
Marking guidance:
Accept reasonable alternative responses.
Question addresses strategies of global application Credit should be given for broad approaches and not specific actions.
Eg "use public transport" is not acceptable, but "promoting/raising awareness of/subsidising public transport" would be acceptable.
Eg "switching off lights" is not acceptable, but "raising awareness/promoting energy conservation" would be acceptable.
