Investments in wind power could yield double digit returns at a good site and if a right turbine and a tower are selected. As a rule of thumb, an average annual speed at the turbine hub height shall exceed 5 m/s to make a wind power economically feasible.
At the current market prices the levelized cost of grid-tie photovoltaic energy is $0.11/KWh, which is on par with recent retail costs of grid power in Alberta plus a portion of distribution and transmission charges that a photovoltaic system helps to avoid.
While keeping money in high interest rate saving accounts yield 1.2% annual returns, investments in grid-tie solar power can generate higher returns, reduce your risks to volatile commodity prices and help the environment. Taking $20,000 out of your 1.2% saving account and investing it in the solar power system that yields 4.1% annual return will generate you additional $27,664 after 25 years compared to the saving bank account balance.
More PV installations in Alberta would allow Dandelion Renewables to leverage even better prices for larger volume orders and to pass even bigger savings to you, our customers. With your support we are confident that photovoltaic energy will become a major contributor to Alberta generation supply mix in the nearest future.
