The power of sunshine
Solar power is perhaps the most commonly used type of renewable energy. The sun's power has been harnessed by mankind due to the fact early civilisation and storing solar pv is a technology that has been around for decades.
There is a major problem of solar pv of course: it is only available in daytime and is reliant on clouds and also the weather. In the northern hemisphere it is doubtful that solar power will ever be ready to provide much of our home energy use nevertheless it can still be harnessed to get a whole host of uses.
Solar powered devices have come along way from the small digital watches and calculators you may remember from childhood. Solar pv can now be useful to power a whole coordinate of devices.
Solar powered chargers can recharge nearly any type of device that takes batteries. Perhaps the most useful for generating energy for our homes but wind energy does include its disadvantages. Windmills, that convert the wind's power into electricity, are very large and are unpopular features on the landscape. Also, they are limited to the quantity of energy they can produce - and when there is no wind there is absolutely no energy production.
Even though we are a long way off from being capable to power the entire nation with wind energy we could provide some, lifting some of the burden from the CO2 emitting power stations.
There are also some wind energy products available for home use. Wind powered lights are for sale to the garden. Rather than just turn wind power into light for electricity, wind turbine powered garden lights store the energy created by the wind within a battery, allowing you to operate the light when needed - even should there be no wind.
There are also wind powered chargers. These hand held wind generators allow you to store wind energy and recharge devices like cellular phones from it. These have the gain over solar powered chargers in that they can recharge devices over-night, consequently devices can be recharged when you are asleep - ready to make use of in the day.
Kinetic Electrical power
Another version of renewable energy is kinetic power. This is taking the wasted energy from mechanisms and deploying it to make electricity. A good example of this is the latest version of hybrid cars. These cars make use of the kinetic energy generated when a car brakes and converts it into electricity that the vehicle can use for an additional power source.
And all sorts of kinetic energy devices are offered. Many of which use human capacity to generate and store electrical power. Wind-up radios are a good example as are torches that work by being shook.

The reason for the initial high level of expense for renewable energies is a technology required to harness them continue to be been developed and may not be easily availability to the public. But if you decide to persevere you can create a big saving down the road from not paying the high bills of the conventional energy providers. Once you'll be able to acquire all the electricity that you need it's possible to sell any surplus.
