World oil and natural gas resources are limited and are running out quickly. Therefore the topic of the day is the use of alternative energy resources that in the near future could replace the current energy resources. The use of alternative energy resources for Latvia could solve very constructive economic problem – dependency on foreign country energy resource providers. One of the newest and effective energy resources is biogas, which can be used in thermal energy, electric energy production, and as a vehicular fuel. This article shows the exploration of biogas production perspectives and potential to be used from agricultural products obtained in Latvia, of which corn ensilage is the most effective one. Since Latvia has huge areas of uncultivated farmland, these areas can be used for efficient corn growing, from which biogas would be obtained, and then reprocessed into electric energy. The statistics show that using 140 thousand hectares or 10% of the European Union agricultural spaces of Latvia for corn growing; the potential biogas gain would be at least 564 million m**3. Reprocessing this amount of biogas, it would be possible to gain 1.184 billion kWh electric energy, which let us replace at least 20% of the imported electric energy, and reduce Latvia's dependency on foreign country electric energy providers.
