3. The new CHP plant at Sobacken outside Borås burns biofuel corresponding to 1.7 PJ every year (1 PJ = 1015 J) which is converted into electricity and district heating. The efficiency of electricity production is 32%. a) How much electrical energy does the CHP plant deliver each year? b) How much heat energy does the CHP plant deliver each year? Assume that all waste heat can become district heating. c) The electricity produced can be used to power heat pumps that heat up housing. How much heat energy corresponds to this, provided that all heat pumps have a heat factor of 4.0? d) If the heat delivered in b) and c) is added together, it will be more than 1.7 PJ. Explain how this may be true.

RQ18-17 Expansionary monetary policy and ER system A country operates under a flexible exchange rate system. When the central bank lowers the interest rate during a recession, investment spending will decrease, the exchange rate value of the currency will increase, and net exports will increase . This change in monetary policy will cause: ? the aggregate demand curve to shift to the right. ? the short-run aggregate supply curve to shift to the right. ? the short-run aggregate supply curve to shift to the left. ? the aggregate demand curve to shift to the left. If the exchange rate was fixed instead, then: ? the effects would all be opposite of those that occured under the floating exchange rate. ? the central bank would not be able to use monetary policy to affect economic activity. ? the effects would be the same as under the floating exchange rate.
